HiPot Safety Enclosures

Cortek Test Solutions DUT HiPot Safety Enclosures, also known as “Personal Protective Equipment” (PPE) are designed to prevent the potential of electrical shock when used properly while conducting electrical safety testing of products. Our HiPot test equipment comes standard with a magnetic safety interlock switch and chassis ground connection that must be wired from the safety enclosure to the HiPot tester or any earth ground connection by the customer for safe operation. A key differentiator of our products is that they are easily scaled in the X, Y and Z axis to accommodate the product’s required testable area within the enclosure. If the size of our standard off-the-shelf units do not work for your application, you can request a quote for a custom size.

The hazards of electrical shock range in severity from tingling sensations to a potentially lethal jolt. Therefore, identifying and eliminating shock hazards is incredibly important when performing electrical safety testing. Various types of product testing include: high voltage test (Dielectric test), insulation resistance test, earth ground continuity test, and leakage current test (Line Leakage) to ensure safety to the end user and to conform to product safety agency standards. Our enclosures easily hook up to most hipot testers.

Q. What is the lead time for the enclosures?
A. The lead time for standard Benchtop sizes is stock to 2 weeks ARO. Enclosures with stands, carts may take up to 3 weeks ARO depending on shop queue. Extra-large and custom units are built to order and typically take 2-6 weeks depending on complexity.

Q. Does the enclosure have an interlock switch?
A. All enclosures come standard with a normally open (N/O) magnetic interlock switch. The interlock switch has a UL and IP67 rating, operating supply current of 500mA and operating supply voltage of 200V. It is the customer’s responsibility to connect the interlock switch to the test equipment, from the terminal block.

Q. What is the terminal block for?
A. The terminal block has 20 positions, some of which are used by CTS:

  • Position 1 – Ground hookup by customer
  • Position 2/3 – Magnetic interlock switch

For Options purchased:

  • Position 4/5/6 – Safety Light
  • Position 7/8/9/10 – Start/Stop switch
  • Position 11/12 – E-Stop switch

Position 13-20 are available for customer hookup to equipment.

Q. What is the 9-pin D-Sub used for?
A. The 9 pin D-Sub is provided as a courtesy for customer equipment.

Q. What voltage can the enclosures be used at?
A. The enclosures were tested with a HiPot Safety tester to 11kV DC.

Q. Is there a model or drawing available?
A. We provide a basic block model with outside dimensions only as requested.
The design is proprietary to Cortek Test Solutions.

Q. Do your safety enclosures come fully assembled?
A. Yes, they are ready to use once the customer hooks up the chassis ground connection and any other options purchased.
