Standby (SB)
The power supply is switched to standby mode when the
control input is shorted optionally via a relay contact, a switch
contact or an NPN transistor with open collector (voltage drop
<1V, current typ. 1.5mA). Alternatively, a voltage of 10 to 30V
(typ. 12V/1.5mA, 24V/5.5mA) can be applied.
If the standby repeals, the power supply starts with a delay of
500ms.
Using the soft start the current and the voltage rises within
100ms continuously to the default set values. Between control
input SB, power input and power output is a reinforced
Isolation of max. 400Vdc.
Inhibit / Interlock (INH)
The power supply is equipped with a control input Inhibit (INH)
to interlock a DC-shutdown of the power supply.
For the nominal operation of the power supply the connections
of the control input "INH" must always be short-circuited.
The power output is switched off as soon as the connection
between the contacts of the control input
INH is interrupted.
If Inhibit is repealed, the power supply starts with a delay of
35ms. Using the soft start the current and the voltage rises
within 100ms continuously to the default set values. Between
the INH contacts applies a current of typical 2mA.
! Warning against damage in case of incorrect connection assignment
Never apply any external voltage to the control input INH. Never connect a resistor to the INH interface.
Between control input INH, power input and power output is a reinforced Isolation of max. 400Vdc.
Signal Inhibit (INH) Interlock
INH is high, as soon as the connection between the contacts of the control input INH is interrupted.

Auxiliary V12V (AUX)
The power supply offers an auxiliary voltage 12V/500mA. The accuracy is ±500mV. Ripple & Noise 30mVpp.
The auxiliary voltage is not affected by the control signals Standby (SB), Shutdown (SD) and Inhibit (INH) and
remains always active. Between auxiliary voltage, power input and the power output is a reinforced Isolation
max. 400Vdc.
DC-OK Relay (DC Power Good)
The signal DC OK has potential-free relay contacts (changeover). The contacts of CON1 Pin2 and CON1 Pin4
are closed (relay coil is energized) when the power output is active. In (SD) shutdown mode, the contacts are
closed.
The contacts CON1 Pin2 and CON1 Pin4 are open when the power output is inhibited by SB, INH, ACF, OT,
FF, OVP or a defective PFC. Contact load (resistive load): 30Vdc/1A, 60Vdc/0.3A, 30Vac/0.5A. Betwenn the
intermediate relay contact, power input and the power output is a reinforced Isolation max. 400Vdc.
