Charge management for 48 V battery

The regulator operates with a nominal battery voltage of 48 V DC, for a minimum indicated voltage of 42 V. The maximum wind charge current is 70 A and the charge voltage is 52.8 V.

The charge is controlled by a microprocessor with voltage and current limitation.

Braking and load shedding

Automatic braking is performed by electromagnetic short-circuiting. It activates from 58 V or at 50 °C for the cooling system, with reset at 45 °C.

The operation includes an external load shedding resistor of 4 kW. Three load shedding resistors are activated successively for five seconds each during interval braking.

Protection and connection

The screw terminals accept cables of 10 mm². The enclosure has external aluminum cooling fins.

With its IP20 rating, this regulator is designed for indoor use.

Integration into a hybrid installation

This model is not a hybrid regulator. It can be integrated into a hybrid system with a battery bank and compatible equipment.

A solar regulator and a wind regulator can be connected in parallel to the same battery bank.

Compatible with

• Can be integrated into a hybrid system using a battery bank and compatible equipment.
• Can be connected in parallel with a solar regulator on the same battery bank.

Compatibility limits

• This regulator is not a hybrid model.
• Intended for indoor use in accordance with IP20 rating.

Precautions

• The external load shedding resistor must be installed horizontally to function effectively.
