Why GracePESDs®?

Permanent Electrical Safety Devices (PESDs) are designed to mitigate risks of arc flash and electric shock by enabling qualified workers to perform the absence of voltage tests without opening the enclosure. They limit exposure to live components and significantly reduce LOTO procedure times by up to 45 minutes. Grace Technologies ChekVolt® and Safe-Test Point PESDs® are designed to enhance safety and efficiency in DC input voltages between 1kV and 3kV.

ChekVolt® and Safe-Test Point™ 3kV PESDs®

Test Up to 3kV with your Standard Voltmeter

Testing voltage for DC systems up to 3kV shouldn’t be a gamble with safety. If you’re working in utility-scale solar power, electric vehicles, electric rail systems, or EV charging stations, you are aware of the danger. Traditional methods for testing voltages above 1000 VDC demand specialized equipment, expose your team to increased electrical hazards and prolong Lockout/tagout (LOTO) procedures.

Features

• Voltage Divider Circuit: Built-in 10:1 voltage divider circuit* limits the voltage at the Test Points (ex. 3kV to 300V), enabling the use of a standard voltmeter.
• Absence of Voltage Testing: Enables safe absence of voltage testing for 3kVequipment at the point of work, in compliance with NFPA 70E standards.
• High-Impedance Protected Test Points: Touch-safe, high-impedance resistors that reduce the current to a few mA.
• Voltage Presence Indication: The 3kV ChekVolt has redundant LED indicators that provide immediate visual confirmation of voltage presence.
• Robust Design: Built with potted construction, enabling extended temperature ranges and shock and vibration resistance.
• Ideal Applications: DC Applications between 1kV and 3kV

ChekVolt® Up to 1000V AC/DC

Grace Technologies announces new ChekVolt device, which allows users to verify voltage presence and test for absence of voltage in one device, all without opening enclosure doors. The ChekVolt is quickly installed through a single 30mm knockout and includes four lead wires potted in the construction–making LOTO in even the harshest environments safer, smarter, and more productive.

The ChekVolt kit comes with the ChekVolt device, clear cap and two labels (flange and horizontal) for flexible mounting options.
