SECO-LARM ENFORCER ST-BT01Q — 5-in-1 12VDC Multi-Purpose Tester Specifications

Specification sheet for the SECO-LARM ENFORCER ST-BT01Q — a 5-in-1 multi-purpose 12VDC tester for voltage, load, polarity, voltage drop, and PTC fuse testing.

Overview

The ST-BT01Q is a compact field tester with 4 LEDs that quickly and easily show the strength of voltage present in most 12VDC applications, plus an illuminated power connector for polarity checks. It performs 5 essential field tests without needing a multimeter.

Features

• Voltage Testing: Check the voltage of power sources easily in the field.
• Load Testing: Apply a simulated 1A or 500mA load to power sources to check voltage under load.
• Polarity Testing: Check wire polarity using the illuminated power connector.
• Voltage Drop Testing: Check the amount of voltage drop over long cable runs.
• PTC Fuse Testing: Check the integrity of PTC fuses (which can test good for continuity but fail under load).
• Selectable load (1A or 500mA switch) to match the device under test and expected voltage drop
• Illuminated power connector clearly displays voltage polarity
• Overheat indicator

How It Connects

• DC plug: Plugs directly into a power source's 2.1mm DC jack for testing.
• DC jack input: Accepts 2.1mm power jacks plugged directly into the unit.
• 12" alligator leads: For testing terminals directly (e.g., battery load testing).
• Test button: Press and hold 2–3 seconds to apply the selected load.

Sample Applications

• PTC Fuse Testing: Select the 1A load to test whether a PTC fuse holds up under load, not just continuity.
• Load Testing: Connect alligator leads directly to battery terminals; apply 1A or 500mA load to check the battery's load capacity, or simulate current draw to confirm a device (e.g., a camera or lock) has enough supply current before installation.
• Voltage Testing: Plug a DC power jack directly into the tester to check a 12VDC power supply's output.
• Voltage Drop Testing: Measure voltage near the power supply, then again at the end of a long cable run, to determine voltage drop.
• Polarity Testing: Use the illuminated power connector alone — blue indicates correct polarity, red indicates incorrect polarity, purple indicates AC voltage present.

Example system: a 12VDC CCTV power supply (e.g., EVP-1SD6P16UL) feeding a 12VDC bullet camera (e.g., EV-133C-DWBWQ) and a 1200-lb electromagnetic lock (e.g., E-941SA-1200) at the end of a cable run — the ST-BT01Q can verify voltage, load, polarity, and voltage drop at any point in that circuit.
