Description
The Aplus PlusShield 2-800N is a specialized power management solution designed to bridge the gap between simple surge protectors and expensive UPS systems. By utilizing a three-stage Automatic Voltage Regulation (AVR) system—consisting of two boost steps and one buck step—this unit ensures that connected devices receive consistent 110V power even when the input voltage fluctuates between -25% and +20%. Its compact form factor and integrated safety features make it an ideal safeguard for modern home and office environments where power quality can be inconsistent.
This product is for:
- Home Office Professionals: Protects desktop computers, monitors, and external drives from the wear and tear of voltage sags and spikes.
- Students and Remote Workers: Ensures stable power for laptops and networking equipment to prevent connectivity drops during brownouts.
- Home Entertainment Users: Safeguards gaming consoles and streaming devices from lightning-induced surges and electrical noise.
- Tech-Savvy Households: Provides a centralized hub for charging mobile devices via the integrated 2.4A USB port while protecting peripherals.
- Budget-Conscious Users: Offers professional-grade voltage regulation at a fraction of the cost of battery-backup units.

Using the PlusShield 2-800N is straightforward and intuitive, featuring a "set and forget" design that requires no complex configuration. The front panel includes clear LED indicators: a green light for power status and a yellow light that illuminates when the AVR is actively correcting voltage. One of its most practical features is the adjustable delay timer, which allows users to set a 2, 10, or 30-second buffer before power is delivered to equipment after a blackout, effectively neutralizing the risk of inrush current damage. At less than 40dB, the unit operates silently, making it suitable for placement on a desk or behind a TV stand.
Compared to standard power strips, the PlusShield 2-800N offers active intervention rather than passive protection. While a basic surge protector only reacts to extreme spikes, this AVR unit constantly monitors and adjusts the voltage to maintain a safe operating window. It is significantly more compact than traditional industrial stabilizers, measuring only 250 x 90 x 87 mm, and adds modern utility with its high-speed USB charging port, which many legacy voltage regulators lack.
Q&A:
- What is the purpose of the 3-stage AVR system? The system uses two boost stages to raise low voltage and one buck stage to lower high voltage, keeping your equipment within a safe 10% tolerance of 110V.
- Why does this unit have an adjustable delay timer? The delay timer prevents the massive surge of electricity that often occurs the moment power returns after an outage from hitting your sensitive electronics.
- Can I use the USB port to charge a tablet? Yes, the smart USB port provides up to 2.4A, which is sufficient for fast-charging smartphones and tablets.
- What happens if the voltage goes outside the safe range? The PlusShield 2-800N features an automatic cutoff that will disconnect the power if the voltage becomes dangerously high or low, protecting your hardware from burnout.
- Does this unit protect against lightning? Yes, it includes 320 Joules of surge absorption and dedicated protection for telephone lines to guard against lightning-induced transients.
