Product introduction:
PDS series intelligent linear adjustable DC
stabilized voltage and current power supply is a high-performance DC power
supply independently developed by our company for the needs of enterprises,
military industry, scientific research, teaching and other units. The chip
control is adopted, and the imported thyristor is used as the power device
to change the voltage at both ends of the rectifier bridge. The original
ximenkang module is used as the voltage regulating and stabilizing device.
The output voltage and current value can be continuously adjusted from zero
to the rated value. The constant voltage and current can be automatically
or manually converted. The protection point can be selected and limited arbitrarily
within the determined range, and the parameters such as voltage and current
can be displayed by LED or LCD. It is widely used in laboratories of
colleges and universities, production lines of DC motors, relays,
resistors, electrolytic capacitors, automotive electronic accessories and
other components aging, product routine test, automatic testing,
communication equipment, automatic aging equipment and other fields
requiring DC power supply.
Product features:
The input
and output voltage specifications of PDS series intelligent linear DC
stabilized voltage power supply can be customized according to the
requirements of the equipment. The company adopts 0.3mm silicon steel sheet
as the design of three-phase five column rectifier transformer with high
power to effectively reduce the harmonic. For the power supply with high
requirements, the company designs six phase or 12 phase output to
effectively reduce the ripple. Compared with the common DC power supply of
input side voltage regulating type and voltage regulating transformer type
on the market, it has the characteristics of high precision and high
stability. Compared with the switching DC power supply, it has the
characteristics of small ripple, small pollution to the power grid, large
single power, high voltage and large current. It has a perfect protection
circuit, more to meet the user's simple, convenient, low-cost operation and
maintenance of the use of demand, widely used in the market.
