YPU - Because you need to be sure



YP-30H PORTABLE High voltage cable & harness tester

- high voltage testing up to 1500 V
- test cables and harnesses that cannot be demobilized to
  the workshop

YPU's robust and field-proven Portable Tester has identical performance characteristics to the YP-30H. The unit incorporates all the capabilities of YPU's larger units into a mobile, wheel-mounted portable rack structure, without sacrificing either quality, reliability or performance.

The YP-30H Portable has been especially developed to meet the needs of field testing for cables and harnesses that cannot be transferred to a workshop, such as those used in submarines, helicopters and warships and airplanes. Thus, besides saving on down-time, units can now be tested in real-time environments. This minimizes the need for disassembly and maximizes testing procedures; it also enables testing of equipment that in the past could not be tested.

  • User-friendly, menu driven software.
  • No programming experience needed
  • Complies with MIL-C3885F (Cable Assemblies and Cord Assemblies Electrical Standard)
  • Applicable to a wide variety of cable lengths and shielding
  • No calibration processes required
  • Performs self-learning of good wired assembly samples
  • Imports wiring lists from CAD/CAM or host computer
  • Includes automatic BIT and initiated self test.
  • Selection of voltage, current or resistance configured for one or a group of chains.


Low voltage continuity and functional testing, and high voltage insulation testing for a wide array of cables, harnesses, slip rings and wired assemblies within minutes.
Test backplanes, circuits and assemblies, and include components for both functionality results and AC signatures.
Modularity provides virtually unlimited scalability
Tests 100 points in less than 5 secs.
High voltage insulation testing (up to 1500 V) within minutes.
Automated bi-directional continuity testing of Slip-Rings in motion.
Conduct tests while controlling switches, relays, LEDs and any other equipment embedded in cables that work using external power supplies.
Modularity provides virtually unlimited scalability.
YPU products are Windows-based, and use 19" industrial PCs or robust portable PCs.
