4. Орнотуу нускамалары

4.1 Таңгактан чыгаруу жана текшерүү

Carefully remove the power supply from its packaging. Inspect the unit for any signs of physical damage. Ensure all components listed in the packaging are present, including the power supply and the multilingual user manual. The packaging uses pearl cotton for protection during transport.

4.2 Input Voltage Тандоо

Before connecting the power supply to an AC source, verify the input voltage switch setting. This switch is located on the side of the unit.

  • Которуштурууну коюңуз 115V for regions with 100-120V AC power (e.g., USA, Canada).
  • Которуштурууну коюңуз 230V for regions with 200-240V AC power (e.g., Europe).

ЭСКЕРТҮҮ: Setting the switch incorrectly can cause severe damage to the power supply and connected devices.

4.3 Электр байланыштары

Ensure the power supply is disconnected from the AC source before making any connections. The unit features a terminal block for both AC input and DC output.

  1. AC киргизүү: Connect your AC power cord to the designated AC input terminals. The terminal block uses cross-head screws for secure wiring.
  2. DC чыгаруу: Connect your 24V DC load to the V+ (positive) and V- (negative) terminals. The power supply provides multiple V+ and V- terminals for convenience.
  3. Негиздөө: Ensure the power supply is properly grounded according to local electrical codes.

5.1 Күйгүзүү

After all connections are secure and the input voltage switch is correctly set, connect the power supply to the AC mains. The power indicator light should illuminate.

5.2 Load Calculation and Selection

To ensure optimal performance and prevent overload, it is crucial to select a power supply with sufficient capacity for your application.

  • For devices with a жумшак баштоо (e.g., most LED lights), the power supply capacity should be at least 125% of the device's maximum peak power (e.g., for a 150W light, select a power supply of 187.5W or more).
  • For devices with a hard start or high inrush current (e.g., heaters, motors), the power supply capacity should be at least 200% of the device's maximum peak power (e.g., for a 150W heater, select a power supply of 300W or more).

The power supply's rated power (1200W) refers to its normal operating capacity under load, not its no-load power. The maximum load should not exceed 80% of the rated current (50A), which is 40A, to ensure longevity and stability.
