The APS-4000 Series storage-type AC power supply is a practical tool for power testing scenarios. Adopting advanced DDS waveform synthesis technology, it ensures stable frequency, continuous waveform, and precise measurement. It is easy to operate, with 110V/220V and 50Hz/60Hz shortcut keys, Key LOCK to prevent misoperation, and M1-M5 five groups of storage for one-key recall of commonly used voltage and frequency. The press-type encoding knob is paired with a four-window five-digit display, synchronously presenting voltage, frequency, current, and power factor for intuitive and efficient data reading.
In terms of performance, it supports measurement of multiple parameters such as voltage and current, and can sustain 300% overload for 2 seconds. It features intelligent alarm for automatic fault judgment and code display; 100% load switching with fast and stable voltage response; input-output isolation and soft start to avoid load power-on impact. Covering multiple models from 350VA to 1200VA, it is compatible with input specifications such as 192W and 162W, flexibly meeting power testing needs in scenarios like electronic R&D, production testing, and scientific experiments, providing stable “power” support for equipment performance verification.

FAQ
How is the unit deployed within an automated test rack or bench environment?
The module is designed for installation as a standalone bench device or rack-mounted unit, where users connect mains input and programme output voltage, frequency and current via front panel or remote control. It functions as a programmable ac power source within wider validation workflows.
What is the warranty and technical support framework offered for high-capacity units?
Matrix provides a defined warranty covering workmanship and calibration drift, along with extended technical support, firmware updates and service kits. This is critical when the product serves as a core ac power source in a long-term verification or production system.
Is the system compatible with existing instrumentation and measurement equipment?
Yes. Standard communication protocols (such as RS-232, RS-485 or USB) are supported, enabling integration with data loggers, scopes and automation controllers. This compatibility allows the unit to serve as a portable power source or fixed system component within a measurement ecosystem.
What lead time should be expected for wholesale or OEM order volumes?
Lead time depends on configuration and quantity, but Matrix maintains production readiness to service wholesale power supply demands. Clients seeking bulk delivery should provide specifications and scheduling early to ensure alignment with manufacturing capacity.
How is operational safety and data integrity ensured in remote or network-connected use?
The unit operates via command-based control and does not store personal user data. Protective features—over-voltage, over-current, over-temperature and short-circuit protection—are built-in to safeguard systems when used as a power source within critical environments. Secure network integration is recommended for remote control setups.
