Power supply 180W 27.6V 6.5A, 27.6V 2A DRC-180B

Buffered power supply for DIN rail – reliable power supply with battery charging function

This buffered power supply from Mean Well's DRC series is a solid solution for systems requiring continuous power, such as security, access control, or monitoring systems. The device combines the functions of a stabilized power supply and a battery charger, ensuring reliable operation even in the event of a mains power failure. The DRC-180B model, with a power of 180W, is designed to operate with 24V batteries.

Design and application

The DRC-180B power supply is designed for mounting on a DIN rail, which simplifies its installation in control cabinets and switchgear. It has two outputs: one with a voltage of 27.6V and a current of up to 4.5A dedicated to the load, and the other with a voltage of 27.6V and a current of up to 2A intended for battery charging. A wide input voltage range (90-264VAC, 127-370VDC) makes the power supply universal and can be used in various installations.

• Two outputs: One for powering devices, the other for charging the battery – increases functionality and flexibility of use.
• Wide input voltage range: Allows operation in various network conditions without the need for additional stabilizers.
• DIN rail mounting: Simplifies and speeds up installation in control cabinets and switchgear.
• Active PFC function: Improves the power factor and reduces harmonic distortion in the power grid.

Safety and protection

The DRC-180B power supply is equipped with a number of protections to protect both the installation itself and the connected devices. These include:

• Short circuit protection (SCP)
• Overload protection (OLP)
• Overvoltage protection (OVP)
• Battery under-voltage protection (UVP)
• Reverse battery connection protection (Reverse Polarity Protection)

Additionally, the power supply indicates the status of the AC mains (AC OK) and low battery level using relay outputs, allowing for remote monitoring of the system status. The operating temperature from -30°C to +70°C ensures reliable operation even in harsh environmental conditions. The device also has a 3-year manufacturer's warranty.
