DC OK Relay Output
If output voltage is decreasing the DC OK relay contact will open. In "normal" output voltage condition the relay contact is closed.
DC OK LED
If output voltage is decreasing the DC OK LED turns off. In "normal" output voltage condition the LED is on.
Alarm LED signaling
If output voltage is decreasing the Alarm OK LED (Red) turns on. In "normal" output voltage condition the LED is off.

Full Function DIN Rail Power Supply
Our high class Power Supplies are fully equipped with all valuable features.
Wide Input Voltage Range AC and DC
Input voltage range of the power supplies is from AC 85 V to AC 264 V or DC 88 V to DC 370 V.
Built-in Inrush Current Limiting
Thermistor (POWER 1AC 24-5), thyristor technique (POWER 1AC 24-10) or active power relay circuit (POWER 1AC 24-20 / 48-10) is used in the inrush current limiting circuit.
Adjustable Output Voltage with Potentiometer
To increase an output voltage, turn a built-in potentiometer clockwise. To decrease the output voltage, turn it counterclockwise.
Hiccup Operation Mode
Hiccup Operation Mode is a behavior of overload protection. In case of output overload or short circuit, the power supply switches off for a short time to restart cyclically (approximately in the range of seconds) again and again and to query the elimination of the overload.
Series Operation
To increase the output voltage you can use the Power Supply in series operation.
Parallel Operation
To increase availability you can use the Power Supply in parallel operation mode. Please use our POWER DIODE modules in this application.
Ultra Slim Dimensions
To save space in your control cabinet, our power supplies are designed to reduce size.
