DTL150 4-WIRE Battery Capacity Tester Electronic Load Instruction Manual

1. Ifihan

The DTL150 is a versatile DC digital electronic load designed for testing battery capacity, power supplies, and other DC equipment. It features a 2.4-inch TFT color screen and supports four primary working modes: Constant Current (CC), Constant Voltage (CV), Constant Power (CP), and Constant Resistance (CR). With a maximum power handling of 150W and a maximum current of 20A, it provides robust testing capabilities. The device incorporates intelligent protection mechanisms and a four-wire connection method for accurate measurements.

1. Asopọ agbara: Connect the provided 12V1A independent power adapter to the working power interface of the DTL150 unit. Ensure the correct plug type (US or EU) is used for your region.
2. Load Connection (Four-wire method for accuracy):
   • Identify the four-wire power terminal on the DTL150 (refer to Figure 1).
   • Connect the positive (+) and negative (-) voltage sensing wires (typically thinner) from your power source/battery to the V+ and V- terminals on the DTL150.
   • Connect the positive (+) and negative (-) current carrying wires (typically thicker) from your power source/battery to the A+ and A- terminals on the DTL150.
   • Ensure all connections are secure using the bolt-style terminals (refer to Figure 2).
3. Load Connection (Two-wire method - less accurate): If a four-wire connection is not possible, you can short the V+ to A+ and V- to A- terminals and connect your power source/battery using two wires. However, this may introduce voltage drop errors.
4. NTC Sensor (Optional): If monitoring the temperature of the power supply, connect an external NTC sensor to the dedicated NTC sensor interface.

• 09. Exit: Exit the system menu and return to the main operating interface.

6.3 Awọn Eto Idaabobo

The DTL150 allows setting protection limits to safeguard your power source. When a limit is exceeded, the device will stop discharging and display a warning.

• Voltage Over-limit Protection: Set a maximum voltage threshold. If the input voltage exceeds this value, the device will stop and display "Voltage Overrun > [Preset Voltage]" (e.g., >30.0V).
• Current Over-limit Protection: Set a maximum current threshold. If the discharge current exceeds this value, the device will stop and display "Current Overrun > [Preset Current]" (e.g., >0.5A).
• Power Over-limit Protection: Set a maximum power threshold. If the discharge power exceeds this value, the device will stop and display "Power Overrun > [Preset Power]" (e.g., >30.0W).
• Stop Discharge Voltage: Configure a minimum voltage at which the discharge test should automatically stop to prevent over-discharging batteries.
• Àkókò ìtújáde: Set a maximum duration for the discharge test.

When a test concludes normally, the interface will display "END".
