A heat-resistant insulator 2 with grooves provided around a support plate 1 fixed by a frame, arranged in a flat coil shape with a distance between each winding to facilitate vertical heat dissipation. It has a fuseless breaker NFB, shorting bars B1 - B7 , and capacity changeover switches S1 - S6 , and various desired voltages and currents can be set by switching these positions. The quasi-load unit is designed to allow easy connection changes depending on the capacity, and has a sandwiching structure in which one end of each support plate can be slid to relieve stress due to thermal expansion of the support plate. Cooling by a fan is used. A pseudo load device for communication power supply testing characterized by a structure consisting of a combination of device units. 2 Various voltages, DC 50V, 48V, DC 21
The dummy load device for communication power supply testing according to claim 1, which is registered as a utility model and has voltages of V, three-phase AC 220V, and single-phase AC 100V. 3. The dummy load device for communication power supply testing according to claim 1 of the utility model registration claim, in which the number of resistors is 6 (N=2). 4. The pseudo load device for communication power supply testing according to claim 1, wherein each pseudo load unit has a structure in which pseudo load units having fine adjustment resistors can be connected in parallel.
