DC-DC Slim SSR DIN Relay

DC-DC Electronic Relay (SSR) Series SRH1 Switching Contact 10A, 15A, 20A, 30A, 40A

Suitable for mounting on a 35mm DIN rail. DC output circuit (anti-parallel thyristors), high number of switching cycles (without arcing of contact material), silent switching, and low control power.

• Long lifespan, no moving parts, no contact burning
• Quiet operation, very advantageous for commercial and medical applications
• Minimal electrical noise due to "zero crossing" switching capability
• Easy control and minimal power consumption for operation
• Resistance to shocks and vibrations, can be mounted in any position
• Fast switching (≤1ms)
• Low weight

Suitable Applications / Segments:

• Heating control,
• HVAC, ventilation
• Lighting
• Motor control
• Mobile applications
• Military technology
• Medical technology
• Food industry
• Smart buildings
• Wind and solar energy
