Detailed Product Description

High Power WireWound Fixed Resistors With Collective Bracket

 

Structure :

 1.The High Power Wirewound Resistor Series includes DDR and DQR(wave-shaped alloy ribbon) and DSR(variable wirewound ).They are called ceramic wirewound resistor,ceramic tube resistor,high power resistor,waved resistor,braking resistor,charge resistor,discharge resistor,dump load resistor,current limiting resistor,aging resistor or load resistor,ect.

2.Several resistors body with collective mounting brackets

3.Single unit with multi-resistance/ Multi-terminals also available;

4.Non-inductive & variable type on requests;

5.Working voltage and Nominal resistance value are related to Ohm’s law.

6.DR series is one core products of ZENITHSUN,owning characters of high power,resistance to shock ,good heat dissipation,high stability,high over load,long life, fast delivery.

 

 

Features:

1.These resistors are suitable as loading resistor,braking resistor,capacitor discharge,resistive load simulation,machinery,machinery and equipment higher power application.
2.Mounting fixture is available.
3.Resistance adjustable version is available:DSR series .
4.Resistance box and load bank available with power up to 2000kW.
5.Support precision resistance tolerance requirement.
