PBI M/MC TR

Dual-source buffer power supplies type PBI M/MC TR

Product description

Mobile buffer power supplies of PBI MC type are intended for operation in direct current power supply systems as power sources for receptions and charging of batteries of rated voltage of 24 VDC. They allow power supply from two voltage sources: 230 VAC and 3x 400 VAC. Constant current receiver’s power supply may be carried out in cooperation with a buffer battery or directly from a power supply.

The power supply is equipped with microprocessor (DSP) converter operation control system and provides a battery status control function.

Features:

Due to application of IGBT transistors in the power supply converter working with PWM pulse width modulation, the power supply features:

High stability of voltages and output currents

Very low current ripple and output voltage

Compact dimensions and weight

Quiet operation and high efficiency

The power supply has protections against:

against overheating of power systems (limits the output current without interrupting operation),

against short-circuit of electronic type,

under- and over-voltage.

The power supply provides:

galvanic insulation from mains,

temperature compensation of the battery voltage,

limitation of battery charging current,

minimisation of interference emitted in frequency due to use of multi-level anti-reference filters,

charging characteristics and cooperation with battery accordant with eurobat characteristics.
