2.2 Физические соединения

Before powering on the device, ensure all necessary connections are made securely.

1. Подключение питания: Connect the supplied power cord to the AC power input on the rear panel and to a suitable AC power outlet. Ensure the voltage selector (if present) matches your local power supply.
2. Load Input Terminals: Connect the device under test (DUT) to the red (+) and black (-) input terminals on the front panel. For high current applications, use appropriate gauge wires to minimize voltagе падение.
3. Sense Terminals (Optional): Для точного объемаtage regulation at the DUT, connect the sense terminals (S+ and S-) to the DUT's output. This compensates for voltage drop across the load wires.
4. Коммуникационные интерфейсы: The DL3031 supports various communication interfaces for remote control and data logging.
• USB-хост: Located on the front panel, used for connecting USB storage devices.
• USB-устройство: Located on the rear panel, used for connecting to a PC for remote control.
• LAN: Located on the rear panel, for network connectivity and remote control.
• РС-232: Located on the rear panel, for serial communication.
• Цифровой ввод / вывод: Located on the rear panel, for external triggering and control signals.

Режимы работы 3.2

The DL3031 offers a variety of operating modes to suit different testing requirements.

3.2.1 Static Modes

These modes maintain a constant load condition.

• CC (Constant Current): Maintains a constant current draw from the DUT.
• CV (постоянный объемtagд): Поддерживает постоянный уровень громкостиtage across the DUT.
• CR (Constant Resistance): Maintains a constant resistance load on the DUT.
• CP (Constant Power): Maintains a constant power dissipation from the DUT.

3.2.2 динамических режима

These modes allow for varying load conditions over time.

• Непрерывно: Provides a continuous dynamic load.
• Импульсный: Generates pulsed load changes.
• Toggled: Switches between two defined load levels.
• Список: Allows programming a sequence of up to 512 steps with different load conditions and durations.

3.2.3 Режимы применения

Access these specialized tests via the ПРИЛОЖЕНИЕ ключ.

• Тест батареи: Designed for testing battery discharge characteristics.
• OCP Test (Over Current Protection): Tests the overcurrent protection of a power supply.
