Краткое описание:
VXI POWER 14854-000 CHARGER, SW MODE, 75W, 28V
Дополнительная информация
Switch mode AC-DC power supply and battery charger provides 75 W output power for fire protection, telemetry, and control applications. The 24 V model provides a 28.6 V main output and a 27.4 V temperature-compensated battery charge output with 2.5 A total shared output current. Universal AC input operation covers 90 V to 260 V rms at 47 Hz to 63 Hz, with typical input current of 2 A at 110 V and 1 A at 230 V. The unit includes battery and load protection, volt-free fault signaling, standby operation, and overload and overvoltage protection. It is designed to meet EN54-4 and is listed as CE and EMC compliant.
