New Yorker Electronics has released Excel Cell Electronics’ (ECE) ESR5 series of Power Type Solid State Relays.

These solid state relays, available with or without LED Indicators, are commonly used in security, industrial, high power equipment, HVAC and control panels.

Offering AC and DC outputs, the relays have a wide variety of available voltages including 60V, 120V, 240V, 280V, 380V and 480V.

Another important feature of this series is that they are optically isolated, meaning they have an array of photo sensors isolating the input from the output side, leading to the ESR5’s low input power consumption.

Other physical characteristics include zero voltage turn-on, zero voltage turn-off to minimise EMI EMI/RFI) and output snubber circuit protection.

The relays also have a high surge rating to allow lamp and motor load switching.

Advantages of ECE’s SSRs to versus electromechanical devices, include low power consumption, low leakage current, stable on-resistance, high reliability, extremely long life and a small size.

They exhibit fast switching speeds, high vibration and shock resistance with no switching noise from contact bounce.

The ESR5 includes an input LED indicator and supplies high DV/DT and a high blocking voltage. It is also both TTL and CMOS compatible.

New Yorker Electronics also supplies the optional ECE Protective Safety Cover.

Being transparent, the cover allows the LED to reach full intensity without being overdriven.
