• Charger

The "SAKY 50 Series" is a power supply for communication equipment that can reliably provide power to critical loads where momentary interruptions are unacceptable. It features a redundant operation system composed of two or more internal charging power units, allowing stable power supply even if one unit fails. Each unit can be easily attached and detached using a drawer-type structure that only requires removing screws from the front. Additionally, it is constructed with a low-noise, high-efficiency switching circuit, achieving compactness and lightweight design. 【Features】 ■ Designed for base stations and relay stations ■ Capable of supplying power to loads stably ■ Extends the overall lifespan of the device while stabilizing output voltage ■ Considers safety and efficiency during maintenance ■ Equipped with a harmonic suppression circuit in the charger to improve input power quality *For more details, please refer to the PDF document or feel free to contact us.

• Other power sources

This is a device that converts noise-free direct current to alternating current for marine navigation instruments. With the technological expertise we have cultivated since our founding, we respond to our customers' needs.

• inverter

We design and manufacture devices that include control for heating power supplies and lift magnet power supplies. Our long-standing track record has led to usage by government agencies as well.

• Power Supplies

It is a small and lightweight converter for DC voltage conversion. Custom-made options are also available.

• converter

The release time is short at 0.1 seconds, and simultaneous reverse excitation is also performed, allowing for the complete release of small items weighing less than 10 grams, while during adsorption, it is possible to supply current to an electromagnet capable of handling large items over 1 ton.
