Phase control type voltage reduction starter with low harmonic noise that does not require a line filter.
The "Powertron" is a phase control type starter that uses a thyristor (SCR) as a switching element, making it very compact in volume and weight, advantageous for space-saving. For soft start matching the equipment being started, the equipment can start without shock, reducing mechanical wear. Especially when the power source is a generator, it can significantly reduce the generator's capacity compared to other starting methods, greatly lowering initial and running costs. Additionally, because it is a non-contact switch, there are no wear parts, which reduces maintenance. 【Features】 ■ Easy fine adjustment, no need for connection tap replacement work ■ Small installation volume ■ Non-contact switch does not degrade even with repeated use ■ No transient current, power, or torque fluctuations occur ■ Easy to increase capacity *For more details, please download the PDF or feel free to contact us.

basic information
【Other Features】 ■ Low noise (no higher-order components due to PWM carrier) ■ Low loss (approximately 3 [W] for control current at low voltage. Efficiency around 99.5 [%]) ■ Easily bypassable during steady operation (input and output phases are in phase) ■ Fewer components ■ No consumables like electrolytic capacitors (for smoothing) ■ No harmonic current generated during full voltage operation (during all-point arcs, non-phase control), so no need for harmonic countermeasures *For more details, please download the PDF or feel free to contact us.
