“Characteristics include its zero voltage turn-on, zero voltage turn-off to minimise EMI and RFI, and output snubber circuit protection. It also has a high surge rating to allow lamp and motor load switching,” according to New Yorker Electronics, which is stocking the parts and sees them bsing used in security, industry, HVAC and control panels.
There is a choice of output voltage ratings: 60V, 120V, 240V, 280V, 380V and 480V, and current ratings: 10A, 12A (60Vdc only), 15A (480Vac only), 25A or 40A. As for the surge rating claim – maximum ratings vary per part number and are between 125A and 400A. New Yorker also emphasises “high dV/dt”, which again varies per part number between 250 and 900V/μs – check the data sheet to make sure.
Operational input current and voltage are also very much part number dependent – example are: 3-32Vdc (16mA max) or 50-280Vac (15mA max).
The photo shows an example SSR without the optional transparent plastic cover. The data sheet shows this pre-installed on 280V and 380V parts (without mentioning the 480V relays) – again, something to check before buying.
New Yorker’s product page is here, through which the data sheet can be downloaded – and you definitely want that to disentangle all the options.
