Description

30 A (RMS) DIN Rail and Panel Mounting Solid State Relays
The CKRD and CKRA series relays come in the industry standard 22.5 mm-wide package. Featuring status indicating LED, DIN rail or panel mount, and "fingerproof" easy to use input and output cage type terminals, all models include integral factory-installed heatsink. Standard models feature zero-cross switching. Options include random turn-on switching (R suffix) and internal transient voltage protections (P suffix). CKRD models have a 4.5-32 VDC control. CKRA models have a 90-280 VAC control and are also available with a 24 VAC control (E suffix). UL, CSA and VDE approved.
It utilize crydom"s proprietary thermal management technology providing a compact and efficient design. Built-in DIN rail attachment, easy-to-use box clamp type terminals and integral heat sinking complete the package. This compact new design offers up to 30 A (RMS) in ambient temperatures of 25 °C.
