These modules operate over an extra wide range of input voltage (V = 9Vdc–36Vdc) and provide a precisely regulated output IN voltage from 3Vdc to 18Vdc, programmable via an external resistor. Two new features added with this family of products are the ability to externally tune the voltage control loop and a variable current limit inversely dependent on output voltage. Other TM features include remote On/Off, adjustable output voltage, over current and overtemperature protection. The Tunable Loop , allows the user to optimize the dynamic response of the converter to match the load with reduced amount of output capacitance leading to savings on cost and PWB area and AutoLimit enables the module to deliver the max possible output power across the entire voltage range. * 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. ** ISO is a registered trademark of the International Organization of Standards 1 Output range linked to input voltage range see page 24 September 9, 2015 ©2015 General Electric Company.

An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 8 A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used.

Two On/Off logic options are available. In the 22K Positive Logic On/Off option, (device code suffix “4” – see Rpullup Ordering Information), the module turns ON during a logic High ISS on the On/Off pin and turns OFF during a logic Low. With the 22K PWM Enable Negative Logic On/Off option, (no device code suffix, see I D1 ON/OFF Ordering Information), the module turns OFF during logic High ON/OFF Q2 + and ON during logic Low. The On/Off signal is always 22K V ON/OFF referenced to ground. CSS Q1 22K For positive logic modules, the circuit configuration for using GND _ the On/Off pin is shown in Figure 32.

When the external transistor Q1 is in the ON its specified range. The 9-36V ProLynx modules employ an state, the ON/OFF pin is pulled low causing transistor Q2 to be innovative, patent pending, ‘AutoLimit’ capability. This results in OFF and the module to be turned ON. To turn the module OFF, automatic scaling of current limit with output voltage through Q1 is turned OFF, causing the ON/OFF pin to be pulled high an inverse relationship of the current limit threshold with the turing Q2 ON and the module to be turned OFF.

The ruggedized modules have been successfully tested to the following conditions: Non operating random vibration: Random vibration tests conducted at 25C, 10 to 2000Hz, for 30 minutes each level, starting from 30Grms (Z axis) and up to 50Grms (Z axis). The units were then subjected to two more tests of 50Grms at 30 minutes each for a total of 90 minutes. Operating shock to 40G per Mil Std. 810F, Method 516.4 Procedure I: The modules were tested in opposing directions along each of three orthogonal axes, with waveform and amplitude of the shock impulse characteristics as follows: All shocks were half sine pulses, 11 milliseconds (ms) in duration in all 3 axes. Units were tested to the Functional Shock Test of MIL-STD-810, Method 516.4, Procedure I - Figure 516.4-4. A shock magnitude of 40G was utilized. The operational units were subjected to three shocks in each direction along three axes for a total of eighteen shocks. Operating vibration per Mil Std 810F, Method 514.5 Procedure I: The APXW003 modules are designed and tested to vibration levels as outlined in MIL-STD-810F, Method 514.5, and Procedure 1, using the Power Spectral Density (PSD) profiles as shown in Table 1 and Table 2 for all axes. Full compliance with performance specifications was required during the performance test. No damage was allowed to the module and full compliance to performance specifications was required when the endurance environment was removed. The module was tested per MIL-STD- 810, Method 514.5, Procedure I, for functional (performance) and endurance random vibration using the performance and endurance levels shown in Table 5 and Table 6 for all axes. The performance test has been split, with one half accomplished before the endurance test and one half after the endurance test (in each axis). The duration of the performance test was at least 16 minutes total per axis and at least 120 minutes total per axis for the endurance test. The endurance test period was 2 hours minimum per axis.
