RX9915A incandescent lamp resistive load cabinet

1. Overview

This load complies with the three load classifications (resistance, capacitive load, incandescent lamp, tungsten filament lamp) in the standards: GB15092.1, IEC61058-1:2016, GB3883.1. It can not only be used as the load required for the life test of the appliance switch, but also as the test load for other similar electrical appliances such as transformers, fuses, plugs and sockets.
2. Technical parameters

2.1. Test voltage: single phase, 0~280VAC manually continuously adjustable, 50/60Hz, at least 45KVA, externally powered by a fast-response variable frequency voltage-stabilized power supply as much as possible

2.2. Basic resistive load

2.2.1. Test current: 1~16A adjustable; power factor (φ) ≥0.98

2.2.2. Resistance adjustable from 0.1Ω~300Ω, minimum resistance change is 0.05Ω, minimum adjustable step range is 0.1A

2 .2.3. Except for the large resistance, the material of the resistance wire is made of constantan wire. The resistance changes little after heating, the current parameters are stable, and it is reliable for long-term use.

2.3. Capacitive/tungsten lamp load

2.3.1. Rated current: 1~16A

2.3.2. Rectifier diode: rectifier bridge with a rated current of at least 1000A

2.3.4. Surge current: 5~256A, in line with the circuit test in Figure 9 of the standard

2.3.5. Surge factor gt;110V, surge factor X=16, <110V, surge factor X=10;

2.3.6. Since the asynchronous switching action time and the power supply waveform will cause differences in each peak value, the peak current adjustment is calculated according to the theoretical calculation value, which is also in line with the actual situation of the switch.
