HIOKI ST5520 Fast Insulation Tester
The HIOKI ST5502 is a fast industrial electrical safety tester designed for insulation resistance testing of electrical devices and components. The ST5520 delivers pass/fail assessment in as fast as 50 ms. The device uses 25 V...1000 V test voltage with 1 V resolution.
- Insulation tester.
- Rapid 50 ms testing speed, 25...1000 V test voltage with 1 V resolution.
- Insulation resistance test up to 9990 MΩ (at 500...1000 V).
- Memory, comparator, timer function.
- Quick discharge of residual voltage.
- Contact check function (prevents errors due to poor contact).
- Short-circuit check function (stops potential defects from reaching the market).
- Ideal for battery production lines.
- Built-in external I/O output, ST5520-01 additional BCD output.
Model Overview
| Model | HIOKI ST5520 | HIOKI ST5520-01 |
| Measurement items | Insulation resistance (applied DC voltage method) | |
| Testing voltage | Measurement range: AUTO/MANUAL setting is possible; 25 V ≤ V < 100 V (2.000/20.00/200.0 MΩ), 100 V ≤ V < 500 V (2.000/20.00/200.0/2000 MΩ), 500 V ≤ V ≤ 1000 V (2.000/20.00/200.0/4000 MΩ) | |
| Basic accuracy | ±2% rdg. ±5 dgt.; 25 V ≤ V < 100 V (0...20 MΩ), 100 V ≤ V < 500 V (0...20 MΩ), 500 V ≤ V ≤ 1000 V (0...20 MΩ) | |
| Measurement speed | Fast: 30 ms/time, slow: 500 ms/time (selectable) | |
| Internal memory | Saved items: Rated measurement voltage, comparator upper/lower limit values, test mode, beep sound to distinguish the result, test time, response time, resistance range, measurement speed; memory capacity: Up to 10 items (can be saved/loaded) | |
| Comparator setting | UPPER_FAIL: Measured value ≥ upper limit value; PASS: Upper limit value > measured value > lower limit value; LOWER_FAIL: Measured value ≤ lower limit value | |
| Judgement process | Beep sound, PASS/U.FAIL/L. FAIL: light up on LED display, When UL_FAIL, U.FAIL/L.FAIL light up simultaneously, EXT I/O output, judgement result can be obtained via RS232C | |
| Test duration | Definition of test duration: Test duration = response time + measurement time; function: Set the time from voltage application until pass/fail assessment; configuration range: 0.045...999.999 s (0.001 s resolution) | |
| Response time timer | After the start of the test, comparator judgment operation can be prohibited until a set interval from 0.005....999.999 s (at 0.001 s resolution) has passed | |
| Analog output | DC + 4 V f.s. | |
| Display | LCD, 4-level backlight | |
| Interface | RS232C (standard), EXT I/O (external control input, judgment result) | RS232C (standard), EXT I/O (external control input, judgment result), BCD output |
| Power supply | 100...240 VAC, 50/60 Hz, 25 VA max. | |
| Dimensions (mm) | 215 x 80 x 166; 1.1 kg | |
Included: HIOKI ST 5520 one of the versions, instruction manual, power cord, EXT I/O connector, connector cover.
