| RDBK | 25 |
| Model | Capacity |
| Control transformer | 25: 25VA
... 5000: 5000VA |
● Aititude not exceeding 2000m
● Ambient air temperature: Maximum temperature does not exceed +40°C,minimum temperature not below -5°C
● Relative humidity: The average maximum humidity in a month is 90%, and the average maximum temperature shoud not exceed 35°C within 24 hours
● The installation place should not have severe vibration and im pact
● In a memium without explosion hazard, and without gases or conductive dust that can corrode metals and damage insulation
● The place protected from rain and snow
● The power supply voltage waveform is close to a sine wave
The coils of this series transformer can bear the full rated capacity when there is only one winding on the primary and secondary sides.If there are multiple windings,the capacity should be allocated according to the capacity that each winding can bear. However, the sum of the capacities of the various windings shall not exceed the total capacity, see Figures 1, 2, 3 and 4.
