Current Limited SSRs with Thermal Management (ThM) and Voltage Triggered Shutdown (VTS)

Specialized OptoMOS® single-pole, normally open Solid-State Relays (1-Form-A) with an integrated current limit feature that can replace electromechanical relays while enhancing the robustness of wireline interface applications. The active current-limit circuitry in these relays also has a thermal management feature that provides excellent power cross immunity for improved survivability in harsh environments. These features greatly improve the robustness of end systems that use these devices, when compared to systems using relays without integrated current limit. These devices may be used in both AC and DC applications.

CPC1540, CPC1563, and CPC1593 incorporate an additional safety feature, Voltage Triggered Shutdown (VTS), that quickly shuts the device down if a voltage transient, above the VTS threshold, occurs in the load while current limiting is in effect. These devices are ideal for use in noisy environments where such transients can be expected.


Features & Benefits:

  • Low drive current
  • High reliability
  • Provides galvanic input to output isolation

Applications:

  • Replace electromechanical relays
  • Replace mechanical switches
  • Implement computer control of electromechanical circuits
