Solid State Relays Accessories.POWER Type UP 62 - .. * Temperature limit switch for overheat protection of small assemblies. Product Description Ordering Key The temperature limit switch is a readily available accessory. It is a thermostat especially designed for overheat protection for small assemblies. again when the temperature drops (approx. 30C) below its cutout value. Thermostat type Switch temperature In the RZ3 relay, the TLS can be connected to two free (internally non-connected) terminals (B1/B2). Type Selection The thermal response is excellent due to its miniaturized housing. It becomes an effective thermal cutout due to the fact that this limit switch can be fitted close to the heatsink of the relay. When connected serial with the control voltage, the TLS will switch off the relay as soon as the operating temperature of the switch is reached. The relay will be activated Thermal compound must be added when inserting the TLS (to guarantee a fast thermal response). UP 62 - 90 Switch temperature UP 62-70 UP 62-80 UP 62-90 70C (158F) 80C (176F) 90C (194F) The heatsink selection charts (load current versus ambient temperature) for RSO types provide information about which thermal switch to use. Installation The UP 62 - .. is mounted in one of the two slots of the 3-phase SSR housing. Specifications are subject to change without notice (30.09.2005) 1
