Littelfuse Releases 1 Amp Fault Protected Solid State Relay
Littelfuse has launched the CPC1561B Solid State Relay (SSR). The CPC1561B is the highest current (1 A, 60 V) normally-open SSR currently available on the market to integrate both current limiting and thermal shutdown circuits.
“The CPC1561B is ideal for markets and applications that cannot be down for long periods due to over current, over temperature and electrical stress,” said Steve Andrezyk, Director of Marketing for Littelfuse-IXYS Integrated Circuits. “The CPC1561B output relay can survive harsh conditions and resume normal operation once the fault is removed, thus reducing product downtime and potentially eliminating service call time as the SSR both protects itself and resets to resume normal operation.”
The small, surface-mount CPC1561B SSR’s dual fault protection benefit provides a rugged solution for demanding applications that is not possible when using electro-mechanical relays and standard SSRs.
Typical markets and applications for the CPC1561B include:
- Smart homes
- Building automation
- Gaming
- Instrumentation
- Battery-powered systems
The CPC1561B offer these key benefits:
- Enhances electronics capabilities to survive fault conditions through active current limiting.
- Adapts to fault conditions using thermal shutdown fault mode protection @ 128˚C die temperature.
- Reduces equipment downtime and high cost of repair by utilizing recovery with auto-reset capabilities, thus avoiding system failures.
- Offers input-output galvanic isolation via 3750VRMS input-to-output isolation.
