“H” Family of hockey puck solid state relays for AC switching applications from 1-90 amps. These relays include a clear safety cover and the Maximum Surge Survival™ technology: 1-90 amp, AC or DC activated solid state relays for switching AC loads |

“HMA” Family of hockey puck solid state relays for AC switching applications from 1-50 or 1-90 amps. The HMA converts the analog 4-20mA control signal into a high speed on/off/on/off control for heaters. The microprocessor-based unit uses a minimum of 3 half sine waves and adds ONs or OFFs to match the required performance. Regular resistive heaters will have an extended life; and high speed loads such as IR heaters and sealing bars will have accurate performance while using electrically clean, noise free, zero-crossing technology: 1-90 amp, analog 4-20mA activated solid state relays for switching AC loads |

“HDD” Family of hockey puck solid state relays for DC switching applications. These relays include a clear safety cover, the Maximum Surge Survival™ technology, RoHS, CE, and Made in the USA. DC switching is common for solar, vehicle, and alternative energy applications, using mosfet or IGBT technology. Switching can be any speed up to 20kHz PWM: 1-75 amp, DC activated solid state relays for switching DC loadsSSR heat sinks, thermal transfer pads, MOVs, parts, pre-installed options |

“C” Family of din rail contactors for applications up to 100 amps. Two pole switching or individual single poles; Maximum Surge Survival™ technology; and flow through wiring. The universal, modular design replaces mechanical, mercury or lighting contactors in industrial, municipal, or military applications. up to 100 amp per pole, AC activated |

Application Notes:
- How to maximize your SSR application — avoid over-voltage, over-amperage, and over-temperature
- Heat sink information, fusing, MOVs, etc.
- Glossary: Mechanical, mercury, solid state relays, SCRs, and phase angle terminology
- How to invert a signal — Normally Open becomes Closed, and Normally Closed becomes Open.
- How to change a control input range — such as reduce your 48VDC to an acceptable control input
