Notes
1. Maximum power with 18 CFM forced air is 250 W, or 200 W with convection cooling.
2. For current share option add suffix ‘C’ to model number.
3. Current share models are built to order.
4. All models require 2 A minimum load on V1. On V2, JPS250PQ46 requires 1 A and JPS250PQ41 requires 0.5 A.
† Available from Farnell. See pages 204-206.
^ Available from Newark. See pages 207-208.

Notes:
1. TB5 is for fan with Molex 5045-02A or equivalent.
2. TB1 (AC input) and TB3 (DC output) are terminal blocks.
3. TB2 signal connector is Molex 70246-10 or equivalent.
4. Maximum mounting screw penetration is 0.16 (4.0) from chassis
outer surface.
5. Fan/Cover option available, order part number:
PQ41, PQ46 & PQ47: JPS250 F/CVR† PQ48: JPS250 F/CVR 24†
or add suffix ‘-E’ to model number to receive unit with cover fitted.
6. PS - Single wire parallel on ‘C’ models only.
No connection on standard models.
Signals
1. To turn off the output, apply 5 V to the remote On/Off.
2. AC OK is a TTL signal which goes LOW when input falls below
60 VAC at rated load.
3. DC OK is a TTL signal which goes LOW when PSU is in an
overcurrent condition, overvoltage condition, disabled or when
output falls out of regulation.
4. For AC OK and DC OK signals, source current is 1 mA, sink
current is 6 mA.
