Note:

1. Applying <0.3 V or short between pins

INH and RTN turns the output OFF.

2. Applying >4.5 V or open circuit

between pins INH and RTN turns

output ON.

3. The output will enter at hiccup mode.

Recommended maximum time is

3 minutes.

Note:

1. Open collector signal: 28 V maximum

voltage and 5 mA (maximum sink current)

Note:

Sink current = 6 mA, Source current = 1 mA

Power is good 100-500 ms after output is in regulation.

Power not good at least 1 ms before loss of regulation.

In order to ensure safe operation of the PSU in the

end-use equipment, the temperature of the components

listed in the table (right) must not be exceeded. See drawing

above for component locations. The temperature should be

monitored using K type thermocouples placed on the hottest

part of the component (out of any direct airflow).
