Type USVD and Type HVD Ultra-Precision Voltage Dividers - 450 Volts to 5 KV

Type USVD Ultra-Precision Voltage Dividers have the very highest precision available in voltage dividers in the range of 450 Volts DC up to 2000 Volts DC. These dividers are formed by bonding together two selected Type USF Ultra-Precision Resistors. The precise selection of these high performance resistors, which form the voltage dividers, makes possible the outstanding voltage division performance. Ratio Tolerance as tight as 0.01% and Ratio tC of 2ppm/°C.

Type HVD Ultra-Precision Voltage Dividers are

monolithic voltage dividers built with ceramic sandwich construction. These voltage dividers have ultra-precision performance in the range of 1500 volts DC to 5000 volts DC, with a Ratio Tolerance of 0.05% and Ratio TC of 5ppm/°C. These dividers are ideal for high performance voltage division applications in medical equipment, laboratory equipment, analytical instruments, etc.
