BL91 series marine excitation variable resistorDetailed product description：

BL91 series marine excitation variable resistor

Purpose:
The BL91 series marine excitation variable resistor is suitable for use in ship electrical equipment circuits with a DC voltage not exceeding 380 volts. It is used for voltage adjustment and regulating the speed of DC motors in power generation excitation circuits.

Structure:
This variable resistor is composed of ceramic resistance elements and conversion devices, both installed in a drip proof box shell. The resistance elements are made by winding resistance wires around threaded ceramic tubes, and the panel is made of glass fiber insulation board with conversion equipment. Bridge contacts are used to change the resistance value by hand wheel. The box type is drip proof, and its structure meets the electrical requirements of ships. The resistor should be installed vertically with the anti bottom cover above.

Ordering Notice:
1. Product model name, resistance value, current value or number, and quantity;
2. Purpose, speed regulation or pressure regulation;
3. Special requirements: Total power, total resistance, total current, divided into several segments, each segment's current, and resistance value need to be provided.
