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 presents the Current Sensing Resistor – a precision, ultra-low-ohm resistor engineered for accurate current measurement in compact electronic systems. Featuring a metal alloy element in a thin vertical package, this Metal Element Resistor delivers extremely low resistance values (from 3mΩ to 100mΩ) with a low temperature coefficient (as low as ±50 ppm/°C) and minimal inductance. Available in 1W, 2W, and 3W power ratings, it is ideal for battery-powered devices, portable instrumentation, power management ICs, and low-power motor controls. The slim profile (4.5mm body height) and flexible lead spacing (10mm–25mm) allow easy integration into space-constrained PCB layouts, while tight tolerances (down to ±1%) ensure measurement accuracy. 

RST Electric presents Non-Linear Load Bank – a precision power testing solution designed for applications requiring realistic simulation of complex electrical loads. Combining resistive (R), capacitive (C), and inductive (L) elements in a single unit, this RCD Load Bank enables accurate emulation of power factors from 0.65 to 1.0, making it ideal for testing inverters, UPS systems, AC power sources, and renewable energy equipment. With three-phase independent adjustment, 0.1kW/0.1kVA load stepping, and ±3% loading accuracy, it delivers exceptional flexibility for R&D laboratories, quality assurance, and production testing. The unit features a touchscreen local interface with real-time data logging and curve display, plus RS485/Modbus-RTU remote control via PC software. Housed in a compact, mobile enclosure with forced air cooling and <65dB noise operation, it suits indoor laboratory and manufacturing environments.

RST Electric presents a high-performance Power Wirewound Resistor engineered for demanding power applications. Featuring a precision-wound element on a high-purity ceramic tube with silicone coating, this Wirewound Resistor delivers excellent stability, high-temperature operation, and inherent non-inductive characteristics. With power ratings from 50W to 10kW and resistance ranges from 0.1Ω to 10kΩ, it is ideal for power supplies, motor drives, medical equipment, and renewable energy systems. Available in ±1% and ±5% tolerances with TCR options from ±50 ppm/°C to ±350 ppm/°C, this High Power Wirewound Resistor ensures reliable performance in both continuous and pulsed load applications. 

RST Electric introduces TO247 Thick Film Power Resistor – a high-power, surface-mountable resistor designed for demanding power electronics requiring superior thermal management. Housed in a standard TO247 plastic package with an integral mounting tab, this TO247 Power Resistor delivers 100W at 25°C case temperature when properly heatsink mounted, making it ideal for high-power switching supplies, pulse loading circuits, power amplifiers, and snubber networks. With a wide resistance range from 0.2Ω to 1MΩ, tolerances as tight as ±1%, and a maximum working voltage of 700V, it offers exceptional versatility for industrial, automotive, and renewable energy applications. The molded plastic case provides high insulation resistance (>10GΩ) and withstands 1800VAC dielectric strength, while the non-inductive thick film construction ensures stable performance in high-frequency circuits.
