Function Test Devices with Built-in Safety Tests
SCHLEICH function test devices combine several electrical safety and quality tests in one compact system. They integrate the protective earth resistance test, the insulation resistance test, the high voltage test, and single or three-phase function test into a single device, making them ideally suited for end-of-line test stands and automated manufacturing processes.
Key Facts:
- Safety and Function Tests in One Device
- Fully automatic execution of the entire test
- Test Voltages from 1 V to 1000 V AC Single-/Three-Phase, DC
- Test currents from 0.1 mA to 1000 A
- Built-in switch-over of test methods without time loss
- Expandable for complex devices under test
- Relay matrices with hundreds of test points
- Ideal for series production tests and EOL tests
- Ideal for type approval tests and quality assurance
- Two-channel Safety Function – compliant with PLe / SIL3
Integrable safety tests
Before the function test is performed, the test device first conducts the safety tests on the device under test (DUT):
- protective conductor resistance
- insulation resistance
- High Voltage
- ARC detection
- leakage current, standard and medical
Built-in Function Test
As part of the function test, the test device first checks for a short circuit between L↔N or L1↔L2↔L3 and then applies a defined operating voltage to the device under test. The following electrical parameters are recorded and evaluated:
- continuity test
- TEST VOLTAGE: undervoltage, nominal voltage, overvoltage
- Current consumption: starting current, no-load current, load current
- Power consumption: apparent power, active power, reactive power
- Power factor (cos φ)
- …
Advantages of the function test device
