Bistable relays – Energy-efficient and reliable switching
IVY Metering relays are a key component in energy meters. They enable motors to be started and stopped smoothly, thereby contributing to improved energy efficiency and extended drive service life. High switching capacity, short response times, and a compact design make IVY Metering relays the ideal choice for modern automation solutions.
Bistable switching technology IM-M1202 relay with motor-driven for high shock and vibration resistance, which is ideal for industrial applications:
1. Zero Contact Welding & High Short-Circuit Withstand (UC3/IEC 62052-11/IEC-62055-31 Standard), Reliable breaking under extreme short-circuit conditions.
2. Anti-Magnetic Theft (Magnetic Immunity 500mT), Resist external magnetic interference, protect revenue and data security.
3. Low Contact Resistance & Low Temperature Rise, High-conductivity contacts for stable performance and energy efficiency.
4. Compact & Space-Saving Design, Optimized size for easy integration in metering and control systems.

Bistable relays can be used to switch applications in a reliable and energy-saving manner. Bistable relays allow for two stable switch positions even when powered down. In comparison to monostable relays, just a short switching impulse of a few milliseconds is enough to switch the relay into a defined switch position. Only a low nominal power level is required. This saves energy and reduces heat generation. In addition, the relays have high vibration and shock resistance.
