$ 69.00
Description
Expert Features
- 2000VA Line-Interactive Protection : Built for personal-computer setups, this UPS uses a line-interactive architecture to keep connected equipment running through short power interruptions and unstable mains conditions.
- Two-Boost + One-Buck AVR : Automatic Voltage Regulation stabilizes a wide incoming-voltage range without immediately consuming battery power, using two boost stages and one buck stage.
- 2–6ms Typical Transfer Time : Fast switchover helps keep PC equipment powered when mains electricity suddenly disappears.
- Dual 12V 9Ah Batteries : The internal battery system uses 2 × 12V/9Ah batteries for a combined 24V DC battery system.
- Microprocessor-Controlled Reliability : Built-in microprocessor control with internal self-diagnostic technology manages the UPS operation and protection functions.
- Off-Mode Charging + Intelligent Recharge : The UPS supports battery charging while switched off and includes a fast intelligent battery-recharge function.
- Generator Compatible : Designed to operate with compatible generator-fed environments, useful where grid interruptions are common.
- DC Start Function : The unit can be started without an active AC supply, according to NCTS’ product introduction.
