Electronics That Protect Health Care Vehicles

We produce components for each electrical system aboard a modern ambulance. Our products include electrostatic discharge suppressors and arc flash relays that ensure patient and paramedic safety, solenoids for emergency lights, and solid-state switches for dc motors. We also offer industry-leading overcurrent and overvoltage protection for batteries and wiring harnesses throughout the vehicle.
