-

On/off control circuit

External isolated NO contact (loading max. 15 V DC/max. 10 mA) is required; opening the control circuit terminates buffer mode.

Methods of setting the buffering time

Adjustable using DIP switches to a maximum buffering time up to forced shutdown at approx. 7 V internal capacitor voltage (output remains constant at 24 V up to that point) or to a time limit of 5 ... 315 s (in 10 s increments) if the energy content is sufficient for the required current

-

Interruption

Adjustable with DIP switch, either:

• Interruption of the output voltage despite returning input voltage for 5 s following expiry of set buffering time to support automatic restarting of Industrial PCs

or

• No forced interruption on expiry of the set buffer time
