Switching DC power supplies are designed for wide usage in industry even in the most difficult conditions e.g. cement works, ironworks, energetics, telecommunications, railways etc.

Power of standard power supplies is in range from 1,2 W to 22 kW, special power supplies to 500 kW. Efficient input circuit protects the power supply against operating overvoltage from mains and optimally designed filter inhibits the interference infiltration to mains. Efficiency course depending on load of power supply output circuit is in wide range almost constant.

Power supplies permanently tolerate load limiting state: no-load run and short-circuit run. They are characterized also by very good dynamic properties, high stabilization coefficient and very low output voltage ripple.

• switching frequency to 65 kHz
• efficiency up to 95%
• insulation strength input - output 4kVac
• output voltage ripple max. 1%
• N2.2 power supplies have the failure signalling (output undervoltage) by voltage-free contact
• the possibility of parallel connection of power supplies
• continuous no-load run and short-circuit protection
• simple installation also on the DIN rail

• any output voltage from 2,8V to 600V DC
• any output current 0 - 200A, specially to 16kA
• input supply voltage 110V AC, 50-60Hz
• potenciometers for output voltage and current adjustment
• output voltage and current adjusting by voltage signal 0-10V or current loop 0(4)-20mA
• remote switch of power supply output
• control possibility (power supplies with microprocessor control system) of output parameters by computer through interface RS 232/485

Power supply version with microprocessor control system with parameter adjusting and monitoring by control panel with LCD display on the front panel.	Power supply version with digital display with parameter by potentiometer on the panel or by voltage input (0-10V).
