Here you can find some of your common questions related to General Purpose Relays, which can help answer your doubts.
Impulse relays are bistable devices that change state with each control pulse and maintain their position without continuous power, while standard relays require continuous control power to maintain their operated state. Impulse relays provide significant energy savings by eliminating standby power consumption in control circuits.
LETOP BIR series impulse relays support switching capacities up to 16A at 250V AC, suitable for heavy-duty lighting and power control applications. We offer various contact configurations from single-pole to 4-pole arrangements to meet different load requirements.
LETOP
impulse relays reliably respond to control pulses as short as 50ms, with 200ms being the recommended pulse duration for optimal performance. The advanced pulse detection circuits ensure consistent bistable switching even with brief control signals.
impulse relay products have passed multiple international certifications, including CE, CCC, ROHS, and others. Products comply with IEC switching relay standards, bistable device requirements, and impulse relay specifications, meeting global market certification requirements.
Yes, we provide professional OEM/ODM custom services for impulse relays. Our engineering team can customize contact configurations, control voltages, switching capacities, mounting arrangements, and environmental specifications according to your specific bistable control requirements.
Minimum order quantities vary depending on product specifications and customization requirements. Standard BIR series impulse relays typically have shorter lead times, while custom bistable control solutions require additional design and testing time. We can provide small quantity supplies for sample and testing requirements.
