CPS-i2000(R2) MANUAL
External Shutdown (SD)
The power supply is set to the Shutdown mode, when the
control input is either shorted 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 shutdown repeals the power supply starts with a delay of
35ms.
Using the softstart the current and the voltage rises within
100ms continuously to the default set values. Between control
input SD and power output is a reinforced isolation of max.
400Vdc and a basic isolation of max. 600Vdc working voltage.
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 and power output is a reinforced isolation of max.
400Vdc and a basic isolation of max. 600Vdc working voltage.
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If Inhibit is repealed, the power supply starts with a delay of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. Control
input INH can only be connected to a floating contact, for example a switch or a relay. Between control input
INH and power output is a reinforced isolation of max. 400Vdc and a basic isolation of max. 600Vdc working
voltage.
