Switchmode voltage regulator
- AC/DC input voltage
- Adjustable output 5...24 VDC, max. 40 W
- Adjustable from external potentiometer
- Short-circuit protection
- Thermal overload protection
- Standard 11-pole relay socket
Advanced features
- The regulator is based on primary switchmode technology to achieve a high efficiency.
- The outputs are adjustable from a front potentiometer in the range 5...24 VDC or from an external potentiometer.
Application
- General voltage regulator for external transformer used in connection with measurement systems requiring fixed stabilized 24 VDC.
- Supply for any other sensors, transmitters or a general variable voltage regulator in the range 5...24 VDC.
- Used as a power efficient pre-regulator for 5 VDC linear regulator (e.g. from 32 V to 8 V).
- Used as adjustable power supply controlled from external potentiometer.
Technical characteristics
- A green LED indicates active output.
- AC or DC input voltages.
- A rectifier bridge allows free choice of polarity for the DC input.
- Mounting for a standard 11-pole socket which can be adapted for DIN rail or plate use with PR’s 7023 adaptor and 7024 mounting keying.
