China factory RXLG aluminum housed braking resistor 60W~2000W, 0.1Ω-10KΩ wirewound dynamic braking resistor, CE RoHS certified, IP20/IP54/IP65 optional for VFD, elevator, crane, servo, UPS & renewable energy load dissipation.

RST Electric presents the Radial Cement Resistor – a high-power, robust resistor designed for chassis or heatsink mounting in demanding industrial applications. Unlike standard PCB-mounted resistors, this Ceramic Encased Resistor features a rectangular ceramic body with both radial leads and integral mounting brackets, allowing secure attachment to metal chassis or heatsinks for superior thermal management. With power ratings from 10W to 50W and resistance values from 0.1Ω to 100kΩ (wirewound/metal film), it is ideal for power supplies, motor drives, battery chargers, and industrial equipment where reliable heat dissipation is critical. Available in tolerances from ±1% to ±10% with a low temperature coefficient (≤ ±250 ppm/°C), this Chassis Mount Power Resistor meets rigorous performance standards including solderability, dielectric withstand, vibration, and endurance testing.

RST Electric introduces the Non-inductive Metal Plate Resistor – a high-performance, low-inductance power resistor designed for demanding applications requiring minimal phase shift and rapid response. Featuring a metal plate element encapsulated in a flame-retardant ceramic housing, this Non-inductive Resistor delivers excellent pulse handling, low resistance values (from 0.01Ω), and stable performance across a wide temperature range. With power ratings from 2W to 7W (single-element) and combined configurations (2+2, 3+3, 5+5, 7+7), it suits current sensing, snubber circuits, high-frequency inverters, and power amplifier applications. Available in tolerances from ±1% to ±10% with a low temperature coefficient (≤ ±250 ppm/°C), this Metal Plate Power Resistor meets rigorous performance standards including solderability, dielectric withstand, vibration, and endurance testing.

RST Electric proudly presents the 500kW 380V Load Bank – a powerhouse solution for largescale AC power validation. Engineered for utilitygrade generator testing, missioncritical UPS systems, and industrial power applications, this 500kW 380V AC Load Bank delivers uncompromising resistive load accuracy with ultrafine step control and multilayer safety protections. Designed for continuous fullload operation, it features intelligent forcedair cooling, a robust IP23rated chassis (outdoor options available), and dual control modes: local HMI touchscreen and remote PC/Modbus interface. Whether deployed in thermal power plants, hyperscale data centers, or offshore renewable energy farms, this load bank sets the standard for reliability and precision. 

RST Electric 6U Portable DC rack-mounted load bank is a high performance resistive dummy load test equipment built in industry standard 19 inch 6U rack chassis. Dual purpose design supports both fixed cabinet installation and mobile on site testing.

RST Electric presents Bare Alloy Current Sense Resistor – a high-precision, surface-mount shunt resistor engineered for ultra-low resistance current sensing in demanding power electronics. Featuring an electron beam welded alloy element with pure copper electrodes, this SMD Current Sense Resistor delivers exceptionally low resistance values (from 0.1mΩ to 5mΩ), ultra-low parasitic inductance (0.5nH to 5nH), and minimal thermoelectric EMF (<1µV/°C). Available in 3W, 5W, and 7W power ratings with industry-standard footprints (2512, 3920, 5930, 2726), it is ideal for automotive battery management systems (BMS), high-frequency switching converters, and motor control applications. Tight tolerances down to ±0.5% and low TCR (as low as ±100 ppm/°C) ensure accurate current measurement across a wide temperature range.
