AC voltage regulator 2229

DCadjustable

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.
