Edition • 2020-01-31T12:18:33+01:00 The IM82-24-20 power supply unit is designed for DC consumers, in particular for the sup- ply of switching and monitoring devices of the TURCK IM, IME, IMS and IMC series. The power supply provides 24 VDC output voltage and 20 A output current. With the po- tentiometer Vout the output voltage can be ad- justed in a range between 22.5…28.5 VDC. The device provides safety extra-low voltage (SELV) according to EN 60950. The power supply can be set to single or par- allel operating mode. ■ Output voltage adjustable 22.5…28.5 VDC ■ Nominal current 20 A ■ Single/parallel operating mode ■ Surge protection ■ Universal operating voltage ■ Mains failure bridging up to 30 ms ■ High efficiency ■ Parallel operation possible ■ Natural air cooling ■ Power-good relay ■ cULus listed ■ Safety extra-low voltage SELV IEC/ EN 60950 ■ SEMI-F47
