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.

High- density front-to-back airflow is designed for minimal space utilization and is highly expandable for future growth. The wide-input 2 standard product is designed to be deployed internationally. It is configured with both RS485 and dual-redundant I C communications busses that allow it to be used in a broad range of applications. These signals and the 5V auxiliary supply are isolated from the main output and frame ground. Feature set flexibility makes this rectifier an excellent choice for applications requiring modular AC to - 48V intermediate voltages, such as in distributed power.

One needs to be careful therefore not the analog voltage levels present on the backplane. If to exceed the 32 byte page limitation of the device. communications are not stopped during this interval, multiple power supplies may respond to specific instructions because the address of the hot plugged power supply always defaults to xxxx000 (depending on which device is being addressed within the power supply) until the power supply configures its address. The recommended procedure for hot plug is the following: The system controller should be told which power supply is to be removed. The controller turns the service LED ON, thus informing the installer that the identified power supply can be removed from the system. The system controller should then poll the module_present signal to verify when the power supply is re-inserted. It should time out for 15 seconds after this signal is verified. At the end of the time out all communications can resume. Predictive Failures Alarm warnings that do not cause a shutdown are indicators of potential future failures of the power supply. For example, if a thermal sensor failed, a warning is issued but an immediate shutdown of the power supply is not warranted. Another example of potential predictive failure mechanisms can be derived from information such as fan speed when multiple fans are used in the same power supply. If the speed of the fans varies by more than 20% from each other, this is an indication of an impending fan wear out. The goal is to identify problems early before a protective shutdown would occur that would take the power supply out of service. October 10, 2016 ©2016 General Electric Company. All rights reserved.
