What is MRC Modular Rectifier and Battery Charger?

The MRC rectifier is designed for applications that require high power adjustable DC voltage. Many MRC rectifiers are connected in parallel to provide a very high power rectifier-charger solution. Output voltage and output current are adjustable between zero and nominal value.

It is suitable for using in projects that require High Power and High Current, in universal battery charging and DC supply applications that require adjustable output voltage and output current, in projects that need parallel connection and redundancy, and for industrial DC motor supply.

How does it work?

MRC modular rectifiers consist of Power Transformer, AC voltage adjusting unit, 3-phase Full-Bridge Diode rectifier unit, DC Filters and microprocessor based electronic control Boards.



Output voltage regulation in MRC modular rectifiers is done on the AC voltage side and with thyristors. The rectification process is done with a 3 phase Diode bridge. Since the voltage adjusting thyristors are switched at zero-crossings of the AC voltage, it does not generate harmonic distortion in the network voltage. Output filters keep DC voltage stable and at low ripple value.

MRC modular rectifiers have the parallel working feature. No external master unit or frame is required for parallel operation.

Microprocessor-based management board that is equipped with sensitive measuring circuits adjusts the output voltage and current values and keeps them constant.

Adjustable DC voltage needs at high powers up to 10 MegaWatts can be met with MRC modular rectifiers.

MRC Modular: Easy, Power boost technology. You are always ready to increase capacity.


Parallel Operation Technology

MRC modular rectifiers have power increasing technology by connecting in parallel. For parallel operation, the inputs and outputs of MRC rectifiers are short-circuited and the communication cable between the devices is plugged. Parallel connected devices operate together as one device and share the load between them. The number of devices that can be connected in parallel is 16 pcs. MRC rectifiers with patented parallel operation technology operate together and simultaneously and provide uninterrupted and safe DC power and battery charging solution at very high power.



Multi-Master Modular System

There is no need a separate master unit to operate MRC rectifiers in parallel. All MRC rectifiers can operate as master. The master unit is selected automatically with patented software protocol. When the master unit is disabled, a new master is selected in less than a second. There is no power interruption during master change. For parallel operation, it is sufficient to be connected communication cable.


Galvanic Isolation Transformer


There is galvanic isolation transformer in MRC rectifiers. Galvanic isolation transformer provides full isolation between AC input and DC output. Voltage of isolation is 2500V. Galvanic isolation transformer provides the adjustment of DC output voltage to requested value and cut off the direct electrical connection between the network installation and DC loads. This feature ensures the detection of earth leakages in DC distribution installations and safe operation.

Earth Leakage Monitoring

MRC Battery Chargers have an Earth Leakage monitoring circuit. The isolation resistance between the DC output (+) and (-) terminals and the ground line is measured. In case of any DC leakage, the warning signal is activated.

Production at All Industrial Voltages (optional)

MRC Battery Chargers are manufactured in all industrial input voltages.

3 Phase + with Neutral connection , 208VAC, 220VAC, 380VAC, 400VAC, 415VAC, 480VAC, 600VAC

The nominal operating voltage of the MRC Battery Chargers is determined at the time of order and cannot be changed later.

Standard type Three Phase input MRC rectifiers can operate in 3 Phase + Neutral (4-wire) installations.

Neutral connection is required for safe operation.

However, for special needs, it can also be produced in accordance with 3-Phase 3-Wired Delta connection installations.
