2N3A3120-D

Description

Parameter Specifications

1. Power Supply: The 2N3A3120 – D operates on a 230V AC power supply with a frequency of 50/60Hz. It has a power consumption of approximately 20W, which is relatively energy – efficient.
2. Output Voltage and Current: It provides a regulated DC output. The output voltage is typically 12V DC, and it can supply a maximum current of 5A, suitable for powering a variety of low – voltage DC devices.
3. Output Ripple and Noise: The output ripple and noise are kept at a low level, usually within ±50mV peak – to – peak. This ensures a stable and clean power supply for sensitive electronic components.
4. Efficiency: It has a high power conversion efficiency, reaching up to 85%. This means less energy is wasted as heat, contributing to overall energy savings and reducing the need for extensive cooling.

Applications

1. Industrial Automation: In industrial settings, it can be used to power sensors, actuators, and small control modules. For example, it can provide power to proximity sensors on a conveyor belt system or small solenoid valves in a pneumatic control circuit.
2. Security Systems: In security applications, it can power cameras, access control devices, and alarm systems. The stable output voltage ensures reliable operation of these critical security components.
3. LED Lighting: It is suitable for powering LED lighting fixtures. The regulated output can maintain consistent brightness and extend the lifespan of the LEDs.

Weight and Dimensions

1. Weight: Approximately 1 kg, which is relatively light and easy to handle during installation and maintenance.
2. Dimensions: It has a compact design, with dimensions of about 120mm (length) x 80mm (width) x 40mm (height). This small size allows it to be easily installed in control cabinets or other confined spaces.

Features

1. Regulated Output: The regulated DC output ensures a stable voltage and current supply, protecting connected devices from voltage fluctuations and ensuring their proper operation.
2. Over – current and Over – voltage Protection: It is equipped with over – current and over – voltage protection mechanisms. In case of abnormal current or voltage conditions, the power supply will automatically shut down to prevent damage to the connected devices.
3. Short – circuit Protection: It also has short – circuit protection. If a short – circuit occurs at the output, the power supply will quickly cut off the output to avoid overheating and potential hazards.

Stability and Reliability

1. Robust Construction: Built with high – quality components and a durable enclosure, it can withstand normal industrial vibrations, shocks, and temperature variations.
2. Long – term Testing: Through extensive long – term testing, it has been proven to have a stable performance over a long service life. The low output ripple and noise, along with the protection features, contribute to its reliability.
3. Compliance with Standards: It complies with relevant safety and electromagnetic compatibility standards, ensuring safe and interference – free operation in various environments.
