CHINT · Machine-tool control transformer
Product overview
The CHINT JBK5 supplies control, signal and work-lighting circuits in machine tools and industrial equipment. Its capacity code identifies the VA frame; primary and secondary winding voltages, and the VA allocated to each secondary winding, must be specified separately. The illustrated nameplate is JBK5-100, 100 VA.
Technical selection summary
| Manufacturer / series | CHINT JBK5 machine-tool control transformer; illustrated JBK5-100 |
|---|---|
| Capacity-code reference | JBK5-40, -63, -100, -160, -250, -300, -400, -500, -630, -800, -1000, -1600 and -2500 correspond to the stated VA capacities |
| Illustrated nameplate | JBK5-100; rated capacity 100 VA; check the actual primary taps and secondary marking |
| Frequency | 50/60 Hz in the retained Global catalogue; 50 Hz in the current Chinese sample; confirm the ordered version |
| Primary winding references | 2026 catalogue lists 220, 380, 415, 440 and 660 V; the selected transformer must carry the required winding/tap marking |
| Secondary winding references | 2026 catalogue lists 6, 12, 24, 36, 48, 110, 127, 220 and 380 V; confirm the voltage and VA allocation of each winding |
| Core / winding construction | Retained Global reference: argon arc-welded core and clamping structure; current Chinese sample: vacuum-impregnated winding insulation |
| Normal ambient reference | −5 to +40 °C; retained Global reference limits the 24-hour average to +35 °C |
| Altitude | ≤2000 m |
| Mounting construction | Use the exact frame drawing; 800 VA has separate vertical and horizontal constructions |
| Standard reference | Q/ZT 205 |
A family voltage envelope is not an interchangeable winding rating: the Global overview’s AC circuit limit of 690 V does not establish a 690 V primary tap on every JBK5. Voltage values outside the Chinese catalogue table require agreement with the manufacturer. For multiple secondary windings, specify the required VA of each; do not assume that each winding can deliver the full transformer capacity. Confirm the catalogue edition and dimensions before installation.
Typical applications
- Machine-tool control-power circuits
- Work-lighting and signal-power circuits with matched winding ratings
