Switchmode voltage regulator 2229 – 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. Connections 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.
