Product Features

40KVA High-Capacity Power Protection

The NPS-AC40T33I provides a 40KVA power capacity for applications requiring high-capacity, continuous power protection for critical electrical and IT infrastructure.

True Online Double-Conversion Technology

The UPS uses online double-conversion technology to continuously regulate the incoming power and provide stable output power to connected equipment. This design helps isolate sensitive loads from common power disturbances.

Three-Phase Input and Output

The NPS-AC40T33I supports three-phase input and three-phase output configurations, making it suitable for commercial facilities, data centers and industrial installations requiring three-phase power protection. The Maxion series can also be configured as 3/3 or 3/1 depending on the installation requirements.

Unity Output Power Factor

The UPS features a unity power factor design, allowing the 40KVA system to provide up to 40KW of active power under appropriate operating conditions.

7-Inch Touch LCD Display

A 7-inch touch LCD provides a convenient interface for viewing UPS operating conditions, system parameters, alarms and status information. The Maxion series also includes IoT functions for enhanced monitoring.

Wide Input Voltage Range

The UPS is designed to operate across a wide input voltage range, helping maintain stable operation in environments where utility voltage fluctuates. The published specification gives a normal input voltage of 380/400/415VAC and a full-load input range of 304-478VAC.

High Input Power Factor

The NPS-AC40T33I has an input power factor greater than 0.99, supporting efficient utilization of incoming electrical power.

Low Input Harmonic Distortion

The Maxion series is specified with input current harmonic distortion below 2% at 100% linear load, helping reduce harmonic impact on the upstream electrical installation.

Parallel Operation

The Maxion series supports paralleling of up to six units, allowing system capacity and redundancy to be increased for applications with higher availability requirements.

Flexible Battery Configuration

The UPS supports configurable battery arrangements, allowing the backup system to be matched to the required load and runtime requirements. Battery configuration should be selected according to the manufacturer’s recommended installation parameters.

Multiple Communication Interfaces

The UPS provides communication and monitoring options designed to support integration with IT infrastructure and power management systems. Available interfaces include USB, RS232, RS485 and dry contact, with SNMP and relay card options available.

Reliable Protection for Critical Equipment

The online UPS architecture is suitable for protecting servers, networking equipment, data center infrastructure, industrial systems and other sensitive electrical loads that require stable and uninterrupted power.
