HOTOTECH | HTBC-1118 | High-Current Short-Circuit Tester

HOTOTECH HTBC-1118 High-Current Short-Circuit Tester

Two short-circuit structure control modes.

• First: resistance <5 milliohm, pneumatic vacuum arc extinguishing short-circuit test structure
• Second: about 1 milliohm to 100 milliohm, or a greater resistance, industrial high-current silver surface contact short-circuit test structure

Analog cell, battery pack, or battery system: direct short circuit, or short circuit with multiple resistances, for safety performance.
