DC-ok Relay Contact
This feature monitors the output voltage, which is produced by the power supply, and is
independent of a return voltage from a unit which is connected in parallel.
Contact closes as soon as the output voltage reaches the nominal value.
Contact opens as soon as the output voltage dips more than 10%.
Short dips will be extended to a length of 250ms on the relay.
Dips shorter than 1ms will be ignored.

Please note:
The DC-ok feature requires that the output voltage reach the nominal (=adjusted) level after
turn-on in order to function to specification. If this level cannot be achieved, the unit will show
an overload condition. The overload signal will disappear as soon as the adjusted voltage is
reached. This is an important to condition to consider particularly, if the load is a battery or
the power supply is used for N+1 redundant systems.

Output characteristic (typ.)
Curve is valid for the 24V unit. Units with
output voltages other than 24V have an
equivalent and proportional performance
Repetitive pulse loading: Multiple pulses can be supported as long as the average (R.M.S.)
output current stays below the specified continuous output current. If it is higher, the unit will
respond with a thermal shut-down.

Internal input fuse
External fuse on input
The unit is tested and approved for branch circuits up to 20A. External protection is only
required, if the supplying branch has an ampacity greater than this. In some countries local
regulations might apply. Check also local codes and local requirements. If an external fuse is
necessary or utilized, a minimum value of B6A or C4A is required to avoid a wrong tripping of
the circuit breaker.
