Available Models: ZX2, ZRBB, ZX18, RDS series, with customizable resistance values (0.5Ω~1000Ω).
ZX2 series resistor
The ZX2 series grid resistors are suitable for circuits with AC voltage up to 660V at 50 Hz or DC voltage up to 440V. They are used for motor starting, speed regulation, and braking. The resistors are of the open type, with a rated heating power of 3.5 kW.
ZRBB Resistor Bank
The ZRBB Series Resistors are suitable for use in circuits with AC 50Hz voltage up to 1140V and DC voltage up to 1000V. They integrate various mechanisms including hoisting, slewing, luffing or main boom, auxiliary boom, gantry travel, and trolley travel into a single resistor unit.
With multiple combination options available, these resistors are not limited by motor types of different mechanisms and can achieve perfect integration across different resistor characteristics. This series has gained strong preference among OEM equipment manufacturers.
