Bellofram Precision Controls
Phase / Voltage Monitors
Single Phase Monitors
Marsh Bellofram single phase voltage monitor relays are designed to ensure the cost-effective reliable protection of critical equipment that is required to operate above a certain minimum voltage for optimum efficiency. Upon installation, the voltage monitoring relays will automatically activate or deactivate as needed to ensure continuous machinery operation at required levels.
UOA Under Voltage Monitoring Relay
The UOA Series Single Phase Under Voltage Monitoring Relay from the ATC Diversified Electronics division of Marsh Bellofram is a family of single phase voltage monitoring relays, designed to ensure the cost-effective reliable protection of critical equipment that is required to continuously operate at voltage levels of up to 240 VAC.
VBA Series Single Phase Monitoring Relay
The VBA Series Single Phase Monitoring Relay from the ATC Diversified Electronics division of Marsh Bellofram is a family of single phase voltage monitoring relays, designed to ensure the cost-effective reliable protection of critical equipment that is required to continuously operate between two voltage limits of up to 240 VAC. Supply voltage is monitored for a preselected under and over limit.
CV Series
The CV-100 and 200 Series from the ATC Diversified Electronics division of Marsh Bellofram is a family of single phase Under/Over Voltage Monitors combined with short cycle protectors used for appliance control. These units employ a user selectable voltage range Set Point switch.
