Notes:
1. TB3 is for fan, with Molex 5045-02A or equivalent.
2. TB1 (AC input) and TB2 (DC output) are terminal blocks.
3. TB4 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:
5 V models: JPS250 F/CVR 5†^
12, 15 & 48 V models: JPS250 F/CVR†^
24 V models: JPS250 F/CVR 24†^
Or add suffix ‘-E’ to model number to receive unit with cover fitted.
6. For current share operation connect signal 0 V (pin 1) between
units and current share (pin 7) between units. For non ‘C’ models
pin 7 (single wire parallel) is not used.
Fixing Holes:
A = #6-32 screw mounting holes
B = M3 x 0.5 screw mounting holes
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.
