4010-01 - Surge Protector Test Set
Description
Bourns® 4010-01 Surge Protector Test Set is a hand-held, battery-operated tester designed to measure the clamping voltage and dc breakdown
voltage of most surge protective devices. The 4010-01 is suitable for testing gas tubes, carbon gaps, MOVs, Zener and avalanche diodes and
thyristor devices, both as components and as complete protectors.
The 4010-01 is a true slow-rise tester because it does not use a pulse transformer. It contains unique test circuitry and a precise 1mA detector.
As soon as 1mA is conducted through clamping type devices, such as MOVs and avalanche diodes, the control circuits removes the test
voltage from the output terminals and displays the clamping voltage on the meter. A low energy capacitive circuit will discharge through
crowbar type protectors, such as gas tubes and carbon blocks, and trigger the detector. The breakdown voltage will be displayed and the test
voltage removed.
Operation
Internal switches for ramp speed and discharge circuit type are accessed by removing the back cover. They are to be set for the intended
application: 200 V/s for laboratory tests or QC type approvals;1000 V/s for high-speed testing or sorting. The IEEE discharge circuit permits
gas tubes to conduct in the arc mode, while the ITU circuit generally allows only glow currents to flow.
Pushing the test button applies a linear ramp to the device under test. Sensing circuitry automatically terminates the test when either the
dc breakdown or 1mA clamping voltage is reached. The test value is maintained on the LCD display until the test button is released.

Notes:
• For P-type thyristor protectors, breakdown voltage VBO occurs at the device zener voltage VZ. Therefore, the tester will measure actual VBO.
• For N-type thyristor protectors, breakover voltage VBO is higher than the zener voltage VZ. For these devices, the tester will measure VZ.
