Specifically designed for automotive, military, marine, aerospace, industrial, test fixtures, and various 12 and 24 volt OEM applications, POWER-GATE devices are engineered to handle shock and high-vibration environments. Our MOSFET-based relays are well suited for switching both large inductive loads and sensitive electronic equipment like power inverters, communications apparatus, or compressors. Unlike conventional mechanical relays, POWER-GATE relays have no contacts to arc, bounce, and degrade over time. Ultra-low trigger current makes POWER-GATE perfect for power sipping electrical systems where battery management is critical. Capable of switching currents between 50 amps and 600 amps and available in small, medium, and large packages (current depending), POWER-GATE may be the solid state switching solution you’ve been looking for.

IMPROVEMENTS AND UPGRADES FROM GENERATION 3:

  • Completely redesigned package
  • Larger posts for improved electrical and thermal conductivity
  • Lower voltage drop at elevated temperatures for greater longevity and reliability
  • Faster opening and closing times
  • Lower operating current
  • Lower minimum operating voltage
  • Shorter maximum response times to under-voltage, over-voltage, and short-circuit conditions
  • Three additional levels of over-current protection (five over-current and one short-circuit in total)
  • Higher threshold for lowest over-current level, allowing for larger surge currents for longer durations
  • Up to four levels of under-voltage shutdowns available
  • Up to four levels of over-voltage shutdowns available
  • Up to two levels of circuit-break shutdowns available with three options for reset
  • Low power indication
  • New fault LED blinking patterns for identifying exact cause of relay opening
  • User-replaceable fuse in the event of a reverse battery connection
  • Remote LED outputs for monitoring of device status and faults
  • Expanded device characterization in specification sheet

Devices can be customized for opto-isolation, latching, external Vcc, external status, logic feedback, and other various features. If you need to switch from a source to a load, and mechanical relays won’t cut it, POWER-GATE may be your solution.
