www.DataSheet4U.com CMR Series Crydoms CMR Series Solid State Relays were developed to offer the advantages of semiconductor switching technology in a compact, self contained package. Quick and easy installation is coupled with low drive power requirements and efficient, reliable power SCR output. Box Clamp terminals and LED status indication complete the package. This compact new design offers up to 65Arms in ambient temperatures of 25°C. Manufactured in Crydom’s ISO 9001 Certified facility for optimum product performance and reliability. APPROVALS: UL, CSA, VDE, CE Mark. MOUNTING OF CMR SERIES OF SOLID STATE RELAYS CMR Series SSRs are designed to fit to an industry standard TS35 DIN Rail. Mounting clip incorporates tabs for screw mounting to panel. MOUNTING TO THE DIN RAIL Locate rail and align with non moveable end of CMR DIN clip Using reasonable force, push CMR in the direction of the arrow shown. REMOVAL FROM DIN RAIL Pull release tag in direction of arrow using blade of screwdriver. MOUNTING CONSIDERATIONS To achieve maximum ratings, there must be a minimum spacing of 1.6 inch (40mm) between the devices in free air. 1.6 inch (40mm) Minimum THERMAL CONSIDERATIONS The CMR power switching range is based on semiconductor technology and therefore generates heat during operation. The following deating curves must be observed before installation. Crydom products are rated for 100% Duty Cycle.

This type of fuse provides extremely fast opening of the circuit. A fuse should be selected that has an I t let-through rating that is less than the I 2 t capability of the SSR,2for the same duration. Transient Over Voltage (P OPTION) MECHANICAL SPECIFICATIONS All dimensions are in inches (millimeters) 1.0 (25.4) 0.75 (19.1) MOUNTING HOLE/SLOT 0.17 (4.3) DIA. U Select "P" option for internal overvoltage protection. At the presence of high voltage transient the output of the SSR will be triggered on, and the transient will be passed on to the load circuit This is a non-degrading method of protection that ensures that other SSR benefits are maintained. Earth Bonding (Grounding) The CKR heatsink is equiped with an earth bonding screw as is required for Class 1 Protection, in accordance with EN 60950 (VDE 0804). Terminations Wire Size • Maximum wire size of AWG#12 (2.5mm) on input and AWG#8 (4.8mm) output terminals. Connections • Ensure that wires ends are stripped to a minimum length of 0.4 inch (10 mm). Recommended Screw Torque Range • 5-6 in lb (0.6-0.7 Nm) on input and 10-15 in lb (1.1-1.7 Nm) on output terminations.
