NDKG、NDKR、NDKS series control transformers are suitable for 50Hz/60Hz AC circuits, used as control power supply for general electrical appliances in machine tools and mechanical equipment, local lighting and indicator lamp power supply.
The NDKG, NDKR and NDKS series control transformers are designed for 50 Hz/60 Hz AC circuits and serve as control power sources, local lighting and indicator power for machine tools and mechanical equipment. The series adds over‑current protection (NDKG), over‑heat protection (NDKR) or both (NDKS) to the basic NDK transformer design.
The document describes operating limits (altitude ≤ 2000 m, temperature –25 °C to +40 °C, humidity ≤ 95 %), structural features, dimensions for each model, and ordering information such as rated capacity, frequency and voltage. This manual is written in Chinese.
| Rated capacity | 100 VA |
|---|---|
| Frequency | 50 Hz |
| Rated input voltage | 380 V |
| Rated output voltage | 110 V (primary), 70 VA, 24 V, 30 VA |
| Dimensions (NDKG‑100) | 85 mm × 64 mm × 6 mm × 10 mm |
The transformer can operate reliably up to an altitude of 2000 m.
Relative humidity must not exceed 95 %.
