Our Process

Our Process: Preparation
Preparation

Once you accept your quote and confirm your order, we prepare by retrieving related parts and components from our inventory. Anything we do not currently have in stock is sourced.

Our Process: Receiving
Receiving

Upon receipt, all parts are visually inspected for damage and then photographed to document their condition. Parts acquired from vendors must meet our quality standards.

Our Process: Initial Testing
Initial Testing

Industrial computer boards and other parts we are equipped to evaluate are tested to verify functionality and discover possible damage.

Our Process: Refurbishment
Refurbishment

Industrial computer boards have all components with low MTBF numbers (such as capacitors and connectors) replaced and are washed in our PCB cleaner to remove dust and grime.

Our Process: Repair
Repair

Industrial computer boards are fully diagnosed and repaired by our engineers. Logs of the problems encountered and solutions implemented are recorded.

Our Process: Final Testing
Final Testing

Industrial computer boards have all I/O connections rigorously tested to ensure that everything is working properly before the board is certified as ready to ship.

Our Process: Shipping
Shipping

After photos are taken to document the exterior condition of the part, it is packaged and sent to the customer. ESD-safe materials are used to protect sensitive equipment on its journey.

These rectifiers complement the CAR2548DC converter, providing comprehensive solutions for systems connected either to commercial ac mains, 48/60Vdc power plants or telecom central offices. This plug and play approach offers significant advantages since systems can be reconfigured and repositioned readily by simply replacing the power supply. The high-density, front-to-back airflow is designed for minimal space utilization and is highly expandable for 2 future growth. The industry standard PMBus compliant I C communications buss offers a full range of control and monitoring capabilities. The SMBusAlert signal pin alerts customers automatically of any state change within the power supply. * UL is a registered trademark of Underwriters Laboratories, Inc. † CSA is a registered trademark of Canadian Standards Association. ‡ VDE is a trademark of Verband Deutscher Elektrotechniker e.V. § Intended for integration into end-user equipment.

Read back delay: The power supply issues the SMBAlert # notification as soon as the first state change occurred. During an event a number of different states can be transitioned to before the final event occurs. If a read back is implemented rapidly by the host a successive SMBAlert# could be triggered by the transitioning state of the power supply. In order to avoid successive SMBAlert# s and read back and also to avoid reading a transitioning state, it is prudent to wait more than 2 seconds after the receipt of an SMBAlert# before executing a read back. This delay will ensure that only the final state of the power supply is captured. Successive read backs: Successive read backs to the power supply should not be attempted at intervals faster than every one second. This time interval is sufficient for the internal processors to update their data base so that successive reads provide fresh data.

Vout_OV_warn_limit (42): OV_warning is extremely useful because it gives the system controller a heads up that the Command Descriptions output voltage is drifting out of regulation and the power supply is close to shutting down. Pre-amative action may be Operation (01) : By default the Power supply is turned ON at taken before the power supply would shut down and power up as long as Power ON/OFF signal pin is active HI. The potentially disable the system. Operation command is used to turn the Power Supply ON or OFF via the PMBus. The data byte below follows the OC and OT_fault_ response (47, 50): The default response for OPERATION command. both OC and OT is auto_restart (hiccup). Each register, individually, can be reconfigured into a latched state. Latched and hiccup are the only supported states. FUNCTION DATA BYTE Unit ON 80 Restart after a latch off: Either of four restart possibilities are Unit OFF 00 available. The hardware pin Remote ON/OFF may be turned OFF and then ON.

The third way to restart is to remove and reinsert at least 2 seconds, and then turn back ON. All alarms and the unit. The fourth way is to turn OFF and then turn ON ac shutdowns are cleared during a restart. power to the unit. The fifth way is by changing firmware from Clear_faults (03): This command clears all STATUS and latch off to restart. Each of these commands must keep the FAULT registers and resets the SMBAlert# line. power supply in the OFF state for at least 2 seconds, with the If a fault still persists after the issuance of the clear_faults exception of changing to restart. command the specific registers indicating the fault are reset A power system that is comprised of a number of power and the SMBAlert# line is activated again. supplies could have difficulty restarting after a shutdown WRITE_PROTECT register (10): Used to control writing to the event because of the non-synchronized behavior of the PMBus device. The intent of this command is to provide individual power supplies. Implementing the latch-off protection against accidental changes. All supported mechanism permits a synchronized restart that guarantees command parameters may have their parameters read, the simultaneous restart of the entire system. regardless of the write_protect settings. The contents of this A synchronous restart can be implemented by; register can be stored to non-volatile memory using the 1.

Changing the output recovering from over-current and over-temperature voltage should be performed simultaneously to all power shutdowns. supplies operating in parallel using the Global Address An overvoltage shutdown is followed by three attempted (Broadcast) feature. If only a single power supply is instructed restarts, each restart delayed 1 second, within a 1 minute to change its output, it may attempt to source all the required window.

The estimates below are believed to be reasonable under Vin_UV_warn_limit (58): This is another warning flag most operating conditions. However, these are typical indicating that the input voltage is decreasing dangerously numbers and not hard bound values that cannot be close to the low input voltage shutdown level. exceeded. In most nominal operating conditions the returned Status_word (79): returns two bytes of information. The values are significantly better than these estimates. upper byte bit functionality is tabulated in the Status_word FUNCTION ACCURACY section.

Vout_OV_fault_limit ± 3% ± 4% of FL Iout_OC_warn_limit Fan_speed (D7): This register can be used to ‘read’ the fan speed in adjustment percent (0 – 100%) or set the fan speed OT_warn_limit ± 5C in adjustment percent (0 – 100%). The speed of the fan ± 3% Vin_UV_warn_limit cannot be reduced below what the power supply requires for ± 3% Vin_UV_fault_limit its operation. The register value is the percent number, it is ± 2% Read_Vout not in linear format. ± 4% of FL Read_Iout Invalid commands or data: The power supply notifies the ± 5C Read_temperature MASTER if a non-supported command has been sent or ±5% Read_Pout invalid data has been received. Notification is implemented by setting the appropriate STATUS and ALARM registers and setting the SMBAlert# flag. If a non-supported read is requested the power supply will EEPROM return all 0x00h. The microcontroller has 96 bytes of EEPROM memory Restart after a lachoff: To restart after a latch_off either of available for the system host. four restart mechanisms are available.

Minimum information command by first turning OFF then turning ON . The third way to be included in this separate EEPROM: model number, to restart is to remove and reinsert the unit. The fourth way is revision, date code, serial number etc. to turn OFF and then turn ON ac power to the unit. The fifth LEDs way is by changing firmware from latch off to restart.

Implementing the latch-off When the FAULT_LED is RED then a fault condition exists and the power supply may not provide output power. The mechanism permits a synchronized restart that guarantees table below further defines these states: the simultaneous restart of the entire system. A synchronous restart can be implemented by; 1. Issuing a GLOBAL OFF and then ON command to all power supplies, 2. Toggling Off and then ON the Remote ON/OFF signal 3. Removing and reapplying input commercial power to the entire system. It is good practice to turn OFF the power supplies for about 20 – 30 seconds in order to discharge all internal bias supplies and reset the soft start circuitry of the individual power supplies.
