2013-09-09 14:30:32| Industrial Newsroom - All News for Today
Measuring 1.38 x 0.43 x 0.94 in., PBK SIP Series includes 1, 3, and 5 W models with single output voltages of 3.3, 5, 9, 12, 15, and 24 Vdc. Units operate at input voltages of 85~264 Vac and also support input range of 100~400 Vdc for high voltage DC-DC applications. All models are designed for 3,000 Vac/1 min input to output isolation, have over current and continuous short circuit protection, and can operate from -40 to +85°C (1 W and 3 W) and -25 to +85°C (5 W) for challenging environments.
