Dielectric Strength
Type tests and factory tests:
Conducted by the manufacturer.
Do not repeat test in field!
Field test rules:
(1) Use appropriate test equipment which
apply the voltage with a slow ramp!
(2) Connect L and N together as well as all
output poles.
(3) Use only AC test-voltages with 50/60Hz.
The output voltage is floating and has no ohmic
reference to ground.

Output characteristic
(typ.)
Curve is valid for the 24V unit. Units with
output voltages other than 24V have an
equivalent and proportional behaviour.
Bonus time
Duration until the output starts dipping. Bonus
Time is hardware controlled.
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.

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.
