[Mitsubishi Electric] - SRE-K Power Supply Voltage Detection Relay (AC100V to AC240V and DC12V to DC100V)

Family ID: MEL-SRE-K

Mitsubishi Electric MS-T/N series SRE-K power supply voltage detection relay that detects simply by connecting to the power supply terminals, suited to changeover to private generation on a power failure and to battery voltage drop alarms. On this type the scale is set at the OFF voltage. Seven voltage designations are available, AC100V, AC120V, AC200V and AC240V for 50/60Hz common use and DC12V, DC24V and DC100V. Output contact 1c rated AC110V 1.5A and AC220V 1A under AC-15 class with 500,000 operation electrical durability, and DC110V 0.2A under DC-13 class with 250,000 operations, carrying current Ith 3A. Input 1.8VA on AC types and 1.7W on DC types. A CCC certified version is available by adding CN to the model name.
