Product Overview

• Part No: 216NG63A, Alternative Code: HESG441635R1
• Brand: ABB

• Category: Rack Power Supply Module216NG63A is a dedicated rack-mounted power supply module designed for ABB REG216 generator-transformer protection platform. It receives external auxiliary power input and converts it into stable multi-channel DC power for the main processing board, analog acquisition board, communication board and other plug-in units inside the protection cabinet. The module integrates overvoltage, overcurrent and overheat protection circuits to prevent secondary damage caused by power abnormalities. It features built-in voltage monitoring and fault alarm functions, ensuring continuous and reliable power supply for the whole protection system, and is an essential spare component for power plant protection cabinet maintenance.
