Philosophy & User Manuals

Why PowerSentrix was built and how to use it effectively.

Device: PWX-12-4422 v2

1 Philosophy

PowerSentrix was built as a managed power service for ISP operations. The goal is not to expose the internal hardware composition, but to give the operator power visibility, alerts, remote service actions and a clear technician workflow.

Remote & BLE port control

Turn individual ports ON or OFF remotely via PowerSentrix NMS, or locally via the BLE app directly from your mobile phone without requiring network access.

Port labeling

Name every output port after the connected device. You always know what runs on which port — no guessing during an outage.

Voltage & current measurement

Voltage and current measurement on each of the 12 output ports, plus total device consumption. Always know the actual power draw of every connected device.

Real-load battery test

Remotely switch the UPS from mains to battery mode. Test the actual (not calculated) battery life under real load — anytime, without physical access.

🌿 Modular & eco-friendly design

Replace only the faulty component yourself — no need to discard the entire unit. Every block (charger, DC converter, control board) is available as an individual spare part. An economical and eco-friendly solution.

PowerSentrix NMS service

PowerSentrix NMS provides central monitoring, history, alerts and mobile fleet visibility as a managed service.

Battery health at cell level

In addition to the main battery connector, the UPS has a 3-pin measurement input placed between 4 batteries — it monitors each cell's voltage independently and detects a weak cell before it causes a failure.

Configurable digital I/O

Inputs IN1, IN2 and outputs O1, O2 are freely configurable. The UPS can serve as a fire or security alarm. Outputs O1 and O2 can switch 230 V circuits.

2 System Overview

The PWX-12-4422 system consists of four main blocks. Each block is a standalone unit that can be ordered as a spare part — replacing one component does not affect the others.

The public manual describes service operation, local control and technician workflow. Internal block diagrams and hardware composition are not part of the public service presentation.

Connector Description
BAT Two-pin connector for battery pack connection (+/−). The system works with 48V batteries (e.g. 4× 12V lead-acid or LiFePO₄).
BAT MEAS. Three-pin measurement connector. The other end is placed between 4 batteries (between each pair of cells), enabling individual cell voltage monitoring and weak cell detection.
WEB/BLE Button with LED indicator. Blinks = WEB management mode active (access via browser or API). Solid = BLE mode for the Android UPS Manage app.
OUT 1–4 (48V) Four 48V DC output ports. Each port is individually switchable and measurable.
OUT 5–8 (24V) Four 24V DC output ports. Optionally connectable to the 48V bus. Each port is individually switchable and measurable.
OUT 9–10 (12V) Two 12V DC output ports. Individual switching and measurement.
OUT 11–12 (5V) Two 5V DC output ports. Individual switching and measurement.
LAN Ethernet RJ45 — connects the UPS to the network for local web management and PowerSentrix NMS.
IN1, IN2 Digital inputs — voltage-free contact (closed/open). Configurable actions on state change (e.g. trigger alarm, change output state).
O1, O2 Digital outputs — relay contact. Can switch 230V AC circuits. Configurable switching logic including response to IN1/IN2 inputs.
Rear panel — configuration Reset button
The rear panel of the device contains a RESET CONFIG button. Holding it for approximately 5 seconds restores factory settings — including the Web Management password. Use this if you have forgotten your access password and have no other way to access device management.

4 Port Management

Each of the 12 output ports is independently manageable — it can be turned off, on, or restarted remotely (PowerSentrix NMS) or locally (BLE app). The operation is executed immediately without physical access to the device.

Special feature: Port Restart

Problem: If you need to restart a device (e.g. a network switch) through which the UPS connects to the network, a simple "turn off then on" does not work — once you turn it off you lose the network connection and cannot remotely turn the port back on.

Solution: The UPS can perform a port restart as a single atomic command: turn off port → wait a set time → turn on port. This entire sequence runs autonomously within the UPS, independent of the network connection. The network is interrupted only for the brief restart period, after which it automatically restores — and remote management is available again.
Operation Available via Description
Turn port OFF Web · NMS · BLE Immediate shutdown of the output port. The device stops receiving power.
Turn port ON Web · NMS · BLE Immediate activation of the output port.
Restart port Web · NMS · BLE Turns the port off, waits a set delay (configurable), then turns it back on. The full sequence runs autonomously — safe even on the port through which the UPS is connected to the network.
