Switchmode voltage regulator
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.
Applications
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.
