Battery Tester DeLOCK 18159 Black/White

The Delock Power supply tester is a robust voltage tester for PC power supplies compatible with ATX, BTX and ITX standards. It displays all supply voltages on a single screen with one decimal place and signals detected errors audibly. The device is intended for hobbyists and for quick functional checks in professional repair or retail environments. Note: Do not connect the power supply to your computer while testing.

Advantages

The tester shows multiple voltages at once on one display with one decimal precision and provides an audible warning if a fault is detected. It supports a wide range of PC power supply connectors and formats, allowing rapid verification of power rail presence and basic functionality. The compact handheld design simplifies use for on-site checks and bench diagnostics.

Suitable for

• Hobby PC builders and technicians performing quick power supply checks
• Repair shops and retail staff verifying used or returned power supplies
• Field diagnostics and bench testing of ATX/BTX/ITX power units

Key specifications

• Voltage source: 20/24 pin ATX connector
• Voltage test range: +12 V, -12 V, +5 V, -5 V, +3 V, -3 V
• Additional signals tested: 5 V Standby (SB), 12 V Power Good (PG)
• Supported connectors: Floppy, HDD, CD-ROM, SATA, 4-pin (P4), 8-pin (Dual-CPU), 6-pin (PCI-Express)

How to use

Connect the tester to the power supply using the corresponding 20/24‑pin ATX connector and attach any additional peripheral connectors required for the test (floppy, HDD, CD-ROM, SATA, P4, Dual‑CPU, PCI‑Express). Power on the supply and read the voltages shown on the display. If the device emits a warning signal, inspect the indicated rails and connectors for faults or unstable voltages. Always ensure the power supply is disconnected from the computer before connecting the tester.

Usage recommendations

Use the tester on a de‑mounted power supply or with the PSU placed outside the computer case to avoid accidental short circuits; follow standard ESD precautions and verify suspicious readings with a calibrated multimeter.
