CM-ESS.1S Voltage Monitoring Relay
Product Description
The CM-ESS.1S is engineered to monitor voltage levels, specifically configured for overvoltage or undervoltage applications. With a rated control supply voltage of 110 - 130 V AC, it utilizes a RMS measuring principle for both DC and AC voltages across four distinct measuring ranges: 3-30 V, 3-60 A, 30-300 V, and 60-600 V. The device operates under the open-circuit principle and allows for an adjustable hysteresis between 3 to 30% of the threshold value.
Constructed with a double-chamber cage connection, the CM-ESS.1S features screw terminals for secure connectivity. Dimensions include a width of 22.5 mm, height of 85.6 mm, and depth of 103.7 mm, with a net weight of 0.164 kg. The relay is designed for a maximum operational current of 4 A at 230 V AC, ensuring reliable performance across its lifecycle with an electrical durability rated at 100,000 cycles.
Additional features include a sealable transparent cover to prevent unauthorized adjustments and a degree of protection rated at IP50 for the housing and IP20 for the terminals. This relay complies with various standards including IEC/EN 60255-27 and UL 508, ensuring it meets both safety and performance requirements.
