SCD integrated power supply is an integrated power supply, charging, discharging, with automatic equalization/floating (lead-acid battery) or automatic constant current/constant voltage (lithium battery) charging mode, can provide power supply for load, and automatically enter the discharge state of load after AC power failure, and conduct overcurrent/undervoltage protection.
The GreenTech SCD series combines AC power supply, battery charging and discharge in a single unit. It automatically switches between AC input and battery output, provides status indicators for power source, battery voltage, and charging state, and includes protection features for over‑current, short‑circuit, and undervoltage conditions.
The document describes physical dimensions, terminal connections, general electrical specifications, and detailed model‑specific parameters for the SCD40 and SCD80 series, including input voltage ranges, charging methods for lead‑acid and lithium batteries, efficiency, and operating temperature limits.

It accepts 90 V–264 VAC at 47–63 Hz or 126–370 VDC.
Yes, the manual states it has output over‑current/short‑circuit protection.
When AC power is absent, the battery can be manually forced to connect or disconnect (optional feature).
Typical efficiency is about 85 % at 220 VAC input, and it operates from –25 °C to 50 °C.
