Power Supply BCS BCS-ZA4820 48V DC 2A Switching Power Supply

BCS BCS-ZA4820 is a compact switching power supply that delivers a regulated 48V DC output with a maximum current of 2A. Designed for low-voltage DC installations, this unit provides stable power conversion in a small footprint suitable for mounting in equipment racks, control cabinets, or alongside security and telecom devices. The device is intended for systems that require a constant 48V source and includes the core features needed for reliable continuous operation in professional and residential applications.

Advantages

The switching topology provides efficient voltage conversion with reduced heat generation compared to linear supplies, improving energy use and reliability. Regulated output ensures stable 48V DC under varying load conditions up to 2A, reducing the risk of brownouts for connected equipment. Its compact housing and standard mounting options simplify integration into existing racks or cabinets, and the design suits continuous operation for systems such as CCTV, access control and small telecom modules.

Suitable for

• CCTV camera systems and video recorders that need 48V DC supply
• Access control panels and electronic door systems
• Telecommunication modules and low-power network devices
• Control cabinets and rack-mounted electronic equipment
• Any low-voltage DC application requiring a regulated 48V/2A source

Key specifications

• Output voltage: 48V DC regulated
• Maximum output current: 2A
• Supply type: switching (SMPS) topology for higher efficiency
• Form factor: compact housing suitable for rack or cabinet mounting
• Intended use: continuous low-voltage DC power for security, access, and telecom devices

How to use

Install the unit in a ventilated area inside an equipment rack or control cabinet, following local electrical codes and safe wiring practices. Connect the AC mains input to a properly rated power source and confirm the input voltage matches the unit's requirements. Attach the DC output to the load using appropriate wiring and polarity, and verify output voltage before connecting sensitive equipment. Allow adequate clearance for airflow and avoid mounting near heat sources. If the installation includes multiple devices, ensure the combined load does not exceed the 2A rating.

Usage recommendations

For reliable long-term operation, use the power supply within its rated current and ambient temperature limits, provide surge protection on the AC input where applicable, and perform periodic inspections of wiring and connectors. When powering critical systems, consider using battery backup or an uninterruptible power supply in conjunction with this unit to maintain operation during mains interruptions.
