APC 40KVA 400VA 3 Phase Easy UPS 3S 3:3 (E3SUPS40KHB2)

APC Easy UPS 3S 40 kVA (model E3SUPS40KHB2) is a high‑capacity three‑phase uninterruptible power supply engineered to provide reliable, continuous power protection for mission‑critical systems, data centres, server rooms and industrial environments. Designed with online double conversion topology, this UPS offers stable, pure‑sine waveform output that safeguards equipment from blackouts, voltage fluctuations and electrical disturbances while maintaining power continuity in demanding electrical setups.

Product Features

40 kVA Three‑Phase Power Capacity

Delivers a rated power of up to 40 kVA (40 kW), making it suitable for supporting medium to large commercial loads, network infrastructure, and essential IT systems with consistent performance.

Online Double Conversion Topology

Operates using double conversion (online) technology to continuously condition incoming utility power and deliver pure sine‑wave output that protects against surges, spikes, sags and frequency variations.

Three‑Phase Input and Output

Supports 400 V three‑phase input and output, ensuring balanced power distribution for three‑phase electrical systems and critical loads in industrial and business environments.

VRLA Internal Battery Configuration

Includes internal VRLA battery strings (e.g., four 7Ah modules) for built‑in runtime support during power outages, providing backup power long enough to maintain operations or safely shut down equipment.

Robust Electrical Design

Equipped with a dust filter and conformance‑coated boards for improved resilience in harsh environments, helping to maintain UPS reliability and longevity.

Wide Voltage and Frequency Range Support

Accepts a wide input voltage range (approx. 304 V to 477 V) and frequency range (45 Hz to 65 Hz), allowing the UPS to operate effectively under varied power conditions.

High Input Power Factor and Low Distortion

Features high input power factor (~0.99) and low total harmonic distortion (THD <3 %) for both input and output, promoting efficient power usage and minimal stress on connected equipment.

Tower Form Factor

Designed in a tower configuration with durable construction and IP20 protection rating, suitable for electrical rooms or dedicated equipment spaces.
