Marsh Bellofram Diversified Electronics Division CV Series Single Phase Over/Under Voltage Monitor

Product catalog summary

Overview: The CV Series from Diversified Electronics includes the CV-100 and 200 Series, which are under/over voltage monitors with short cycle protectors for appliance control. These devices feature a user-selectable voltage range set point switch to match line voltage for optimal operation.

Functionality: When line voltage deviates from the preselected range, the internal relay disconnects the appliance to prevent damage. Once voltage normalizes, a five-minute delay occurs before the appliance restarts. LED indicators provide status updates: a green LED indicates normal conditions, while a red LED signals a fault. The red LED flashes during the delay period after a fault is corrected.

CV-XXX-AFN Series: This series monitors under voltage only, lacks LED indicators, and includes a five-minute short cycle delay. It is epoxy encapsulated for environmental protection.

Specifications:

CV-100RS: Available for 110 and 120 VAC with a 15A run and 40A lock rotor output rating.
CV-200RS-15: Available for 230 and 240 VAC with a 15A run and 52A lock rotor output rating.
CV-200RS-20: Available for 230 and 240 VAC with a 20A run and 72A lock rotor output rating.
CV-120-AFN, CV-230-AFN, CV-240-AFN: Under voltage monitors with 20A run and 52A lock rotor output rating, featuring quick disconnect terminals.

Dimensions: The CV-100RS measures 1.5" x 2.65" x 3.75"H.

CV Series Diversified Electronics atcdiversified.com 800.727.5646 272HVAC Controls // CV Series The CV-100 and 200 Series are Under/Over Voltage Monitors combined with short cycle protectors used for appliance control. These units employ a user selectable voltage range Set Point switch. This switch should be positioned to match the line voltage for proper operation. When the line voltage goes below (brown out) or above the preselected operating range, the internal relay drops out removing the plugged-in appliance from these adverse fault conditions. When the voltage returns to the normal operating range, a five (5) minute delay begins. Upon completion, the internal relay picks up allowing the plugged-in appliance to start. LED indicators give an immediate visual reference as to the status of the control. The GREEN LED indicates conditions are normal. When a fault condition occurs the GREEN LED will extinguish and the RED LED will glow. When a fault condition has been corrected, the RED LED will begin to flash. The RED LED will continue to flash until the five (5) minute delay period elapses. At the end of the delay period the RED LED will extinguish and the GREEN LED will glow. When both LED’s are extinguished, a total loss of power is indicated. The CV-XXX-AFN Series monitors under voltage only and do not feature LED indicators. They also incorporate the five (5) minute short cycle delay. This style is epoxy encapsulated to protect against adverse environmental conditions.
