Main product range
Develop and produce switching power supplies and battery chargers in a small number and personal needs, as well.
Produce industrial measuring and controlling equipments by special order.
We have been developing power supplies in various parameters for 16 years. (ie. 5, 12, 24, 48, 110, 220, 400, 600 Volt output voltage, 2W - 4kW output wattage.) The input voltage would be 230 Volt AC or 12-24 Volt DC, etc. All of our products are closure-proof, have current limit, the stability of output voltage is 1 percent.
Short description of switching power supplies
Advantages: compact, good efficiency, fine control.
After rectification and filtation the line power would be transformed to high-frequency alternating current by switching transistors. This output would be transformed to the required voltage level by small trasformators, rectificator and clarifier. The output current and voltage are controlled by PWM modulation card. The isolation between primer and secunder side is ensured by isolated (4 kV) tramsformators. The thermodetector transistor checks the temperature of rectificator's heatsink.
The function of the battery chargers is making the required voltage and current to charge batteries from houshold power or other DC. The nominal battery's voltage would be 6, 12, 48 or 60 Volt.
Type of our charger products
High voltage power supply
- IU characteristic: charging with permanent current and - when the voltage reaches the required level - permanet voltage.
- IUu characteristic: charging with permanent current and - when the voltage reaches the required level - permanet voltage. After decreasing of the current charging with constant drop voltage. The advantage of this method: you can leave the battery on the charger.
- IUuu characteristic: similar to item 2. but there is a raised voltage conditional chraging period with limited current for limited time before the drop voltage charging.
35 kV - 3 mA power supply; adjustable output voltage and current.
High Voltage High frequency generator
350Khz 6000V AC output voltage, total output power 100W.
