Bistable relays – Energy-efficient and reliable switching
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.
IVY specializes in the development and manufacturing of high-quality latching relays(bistable). We offer a line of latching relays spanning for single-phase Two-phase and three-phase switching purposes. our relays meet the industry's highest performance standards and offer the best value in the energy management market. In particular, we have developed an innovative bistable relay-motor latching relay.
