The PS5R-V line of DIN-rail power supplies includes 7.5-, 10-, 15-, 30-, 60-, 90-, 120- and 240-W versions. All models have a compact form factor, with overall dimensions reduced by up to 25% from previous generations. Operating temperature ranges from -25 to 75 °C. This extended temperature range means that the power supplies often can be used in control panels without the need for air conditioning or other cooling devices. In addition, operating efficiencies have been improved, up to 16% from previous generations. Flexibility is designed into the power supply line with spring-up screw terminals that accept ring and fork terminals, as well as stripped wire.
