20W Dual 12V Maintenance Power Supply — 12VX2 840MA A reliable maintenance power solution for technicians and system builders. This active computer transformer delivers two 12V outputs at 0.84A each (12V x 2, 840mA), with a combined power capacity of approximately 20W. It is designed to provide stable 12V service power during repairs, testing, or temporary operation of small devices. Key benefits Provides dependable 12V power during maintenance and troubleshooting to prevent downtime and data loss. Dual outputs let you power two independent 12V circuits at once without needing extra adapters. Active transformer design supplies consistent voltage under load for reliable testing and temporary operation. Main specifications Output voltage: 12V x 2 Output current: 0.84A per output (840mA) Total power: 20W Type: Maintenance power supply / active computer transformer Model/reference: 12VX2 840MA What this unit solves Replaces or supplements onboard 12V supplies when a computer or device cannot be powered from its native source during service. Simplifies bench testing by offering two separate 12V rails for peripherals, drives, fans, or control boards. Eliminates the need to repeatedly swap singleoutput adapters when servicing multiple 12V components. Compatibility and typical applications Compatible with equipment and components that require 12V and draw up to 0.84A per rail. Ideal for computer maintenance, boardlevel testing, and temporary power during component replacement. Useful for small electronics, CCTV modules, routers/switches, LED modules, fans, and other 12V peripherals. Use cases 1) Server or desktop maintenance — provide stable 12V to fans, SATA enclosures, or auxiliary controllers while the main PSU is removed for replacement or diagnosis. 2) Bench testing and diagnostics — power two 12V circuits simultaneously (for example, a drive and a controller board) when validating repairs or firmware updates. 3) Small systems and field service — temporarily power network equipment, CCTV cameras, or embedded devices during onsite troubleshooting or installation. Installation and handling notes Confirm device current requirements do not exceed 0.84A per output. Observe correct polarity and connector compatibility when connecting to target equipment. Intended for maintenance and temporary powering; evaluate continuoususe requirements against the 20W rating. This 20W Dual 12V Maintenance Power Supply (12VX2 840MA) is a practical, straightforward tool for technicians and installers who need reliable, dual 12V output for testing, repairs, or temporary operation.
