A fuse on the ac power connector limits the input current. This feature provides short-circuit and overload protection. Recovery is automatic after removal of the overload condition. Test points are conveniently located on the front panel to allow monitoring the status of the dc outputs. When the temperature of the heat sink exceeds 95 C, the power supply is automatically turned off.
Recovery is automatic when the load is reduced and the temperature decreases to a safe value.
Measurements are made within a 1-minute period. Range typically 1 V about the nominal supply voltage. When the heat sink temperature exceeds the 95 C maximum limit, a thermal switch automatically turns off the power supply. Recovery from thermal shut-down is automatic once the load is reduced, so that the heat sink temperature drops below the maximum operating limit. This feature provides short-circuit and overload protection.
