2V63 Single Phase AC/DC Voltage Relay
The 2V630 / 2V631 series are solid state voltage sensing relays with electromechanical output contacts built in a fully draw out case format. Designed for application on AC & DC voltage systems, these relays are ideally suited to monitor power supply voltage levels wherever high accuracy and reliable, maintenance free operation is essential. All power to operate the relays is derived from the sensed input voltage therefore an auxiliary supply is not required. The output relay operates when the input voltage exceeds the pickup setting (P/U) and visual indication is proved by a mechanical hand reset flag or red self reset LED on the front panel. The output relay will reset when the input voltage drops below the drop out voltage (D/O). The relay may be specified with a pre-set fixed D/O level or as an adjustable setting value displayed as a percentage of the selected pickup voltage.
• The 2V630 version is designed for AC voltage operation
