Description

The ULH300F precision shunt resistor from RARA has a 4-terminal metal-clad design, distinguished by a high load capacity of up to 500A as well as excellent accuracy. Isolated voltage and current connections make them suitable for very precise current measurements. Current measurement is made easy by attaching the current bus directly to the source while connecting the flexible voltage measurement wires to your monitoring electronics. Units have low inductance, heavy copper terminals. The ULH F series has a temperature range of -25°C to +100°C with a temperature coefficient of up to 30ppm/°C [20°C to 60°C].
