![]() Pluggable Terminal Block 5.08 mm, 3 Positions ![]() If you got an EMC-PS50 without the mating plug, this is the part. Look for "Pluggable Terminal Block" with 5.08 mm pitch spacing and 3 Positions. Whatever manufacturer, it needs to be able to take a minimum 18 AWG conductor, 250v at 1A. REMOTE Connector
+5V EXT Current limited +5V output with max of 1A. GND This is chassis/logic ground. All of these signals occur as pairs (+ and -). Output signals will provide an uncommitted optoisolator collector/emitter, rated at 50V max, 50mA max. The phototransistor conducts whenever the particular condition exists. Therefore, applying 5V to the + signal and GND to - signal will provide a TTL level output. Input signals require a 5V potential to be applied across the pair to signal the condition. FLT FAULT output when 5V output falls below 4.6V. OT OVERTEMP output when heatsink temperature exceeds 80* C. SD SHUTDOWN input remotely turns PSU on or off. Active only when front-panel power switch is in ON/REMOTE position. As long as a 5V potential exists across these two lines, the PSU will remain in standby mode and will not provide power to the backplane. When the potential no longer exists, the PSU will again power the backplane. IRQ INTERRUPT input signals IRQ15 on backplane. This is a buffered (inverted) input. Since IRQs are positive edge-triggered (with pull-up resistors), to signal the interrupt, apply a voltage across these 2 lines for a minimum of 100 microseconds. This sets IRQ15 low. When the power is removed, the pull-up resistor returns the line to +5V causing a positive edge which triggers the interrupt. RST - RESET input signal causes remote hardware reset of CPU on backplane. Rear Connector 15-pin male T&B/Ansley 371-21530-305X (or equivalent). The female connector is a T&B/Ansley 376-21530-095X (or equivalent). The signals are:
Cooling Requirements The unit is convection cooled, so no forced air in or around the unit is required. However, the system should be installed so that a minimum of 5" of air space is provided on each of the three exposed sides of the power supply unit. The heatsink temperature must not exceed 80°C. |
