Hi-pot, insulation resistance and ground continuity testers — the final electrical safety gate for batteries, chargers, inverters and power equipment.
Electrical Safety
Verify Insulation. Prevent the Shocking Failure.
The VT-ESA series performs the full suite of electrical safety tests required by IEC 61010, UL and GB 4706: AC/DC hi-pot, insulation resistance and ground continuity — with pass/fail decisions in seconds.
- ✓ AC hi-pot to 5 kV, DC hi-pot to 6 kV, 10 mA leakage
- ✓ Insulation resistance to 1 TΩ at up to 5 kV test voltage
- ✓ Ground continuity: 30 A, 0.001–0.5 Ω range
- ✓ Ramp, dwell and discharge control per test standards
- ✓ Remote PLC I/O, RS-232 and Ethernet integration

Key Features
Safety Testing You Can Automate
High Voltage Range
AC 5 kV and DC 6 kV output covers EV pack and industrial equipment requirements.
Precise Leakage
Leakage current measured to 10 µA resolution with arc detection for insulation faults.
Fast Test Cycle
Sub-second ramp and measurement cycles keep production takt times low.
Safe Discharge
Automatic DUT discharge after hi-pot protects operators and downstream equipment.
Programmable Steps
Sequence hi-pot, IR and ground tests into one key-press program per product.
Data Logging
Store results by serial number and export to MES for full production traceability.
Interlock Safety
Two-hand start, door interlocks and e-stop as standard for operator protection.
Rack Integration
19-inch rack-mount options integrate directly into existing test benches.
