No supply voltage (e.g. upstream protection device has opened) or device is defective.
The output voltage is within the tolerance.
The device is working at the current limit (max. 10 A) or at the power output limit (max. 120 W).
(connected load: 0.5 to 2.5 mm
Function
Input voltage 120/230 V AC
Protective conductor
Necessary jumper for the working range 93 to 132 V AC
Output voltage 3 to 52 V,
Max. output current 10 A (in the range 3 to 12 V),
Max. output power 120 W (in the range 12 to 52 V)
(connected load: 0.14 to 1.5 mm
Function
If the jumper is fitted (as-delivered status), output voltage can be set by means of the potentiometer U
jumper not fitted, remote setting of the output voltage by means of the voltage signal at terminal X2-2 (signal
ground terminal X2-9); here, a voltage signal of 0 to 2.5 V
Sense cable connection: enables compensation of voltage drops due to cable resistance. Maximum voltage
correction 0.5 V per cable.
Terminal not assigned at the present time (without any function)
Power-good signal: floating relay contact is closed if the output voltage is within the tolerance (closed-circuit-
current principle). For technical functioning, see Fig. 2 (Page 7)
Reset signal: Open-collector (30 V, 20 mA); is activated when the voltage at the input falls below the minimum
voltage and is set at least 1 ms before breakdown of the output voltage (signal ground terminal
technical functioning, see Fig. 2 (Page 7).
Ground connection for signals at terminal X2-2, X2-8, X2-10 or X2-12.
Current monitor signal: 2.5 V typically correspond to an output current of 10 A +/- 5% (signal ground X2-9).
If the jumper is fitted (as-delivered status), output voltage can be set by means of the potentiometer I
If jumper is not fitted, remote setting of the current limit by means of voltage signal at terminal X2-12 (signal
ground X2-9); here, a voltage signal of 0.5 - 2.5 V
