CCTV Open Power Supply 10Amps

CCTV Open Power Supply 10Amps

The CCTV Open Power Supply 10Amps provides a single power output for CCTV equipment. PowerSupply1 rates the unit at 240W. Moreover, the unit uses a switch to support two AC input ranges.

The power supply contains high-quality capacitors and several safety features. Therefore, it offers steady power for long-term CCTV use.

Tested Power Performance

PowerSupply1 runs every unit through a full-load burn-in test before shipping. This test checks performance at full power. As a result, it helps confirm that the unit can handle a heavy load.

The output voltage also allows a ±10% adjustment. Therefore, installers can fine-tune the voltage when required.

Switchable AC Input

The input switch supports two AC voltage ranges. Installers can select either 85–132V AC or 170–264V AC.

However, the installer must choose the correct range before applying power. An incorrect setting may damage the unit.

The power supply also accepts an input frequency from 47Hz to 63Hz. Therefore, it can work with several mains power systems.

Built-In Safety Features

The unit protects itself against excess load and high output voltage. During an overload, it limits the current. It then returns to normal after the fault clears.

In addition, the unit provides the following safety levels:

• Overload protection: 110% to 130%
• Overvoltage protection: 115% to 150%
• Auto recovery after an overload
• Input-to-output isolation: 3.0kV AC for one minute
• Input-to-ground isolation: 1.5kV AC for one minute
• Output-to-ground isolation: 0.5kV AC for one minute

Start-Up and Power Hold Time

The power supply reaches its output in about 50ms at full load. Moreover, it holds power for about 20ms after an input loss.

These values apply under typical full-load conditions. Therefore, actual results may vary with the connected load.

Working Conditions

The unit works within the following ranges:

• Working temperature: -10°C to 50°C
• Working humidity: 20% to 93% RH
• Storage temperature: -20°C to 85°C
• Storage humidity: 20% to 93% RH
• Humidity condition: No condensation
