What this product is
What this product is
The ZXDT02-PU V2.5 is a modular supervisory motherboard incorporating a dedicated 32-bit industrial MCU/DSP with multi-channel galvanic isolation. It integrates high-precision signal-conditioning circuits for analog telemetry (DC bus voltage, shunt current, load branch current, and battery string thermal tracking), isolated CAN bus interfaces for high-speed rectifier autonomous load-sharing, isolated RS485 ports for peripheral sensors, Fast Ethernet transceivers for TCP/IP, SNMP, and HTTP networking, hardware watchdogs, and an industrial-grade non-volatile flash storage array for persistent system logging.
What problem it solves
Eliminates centralized telemetry blind spots, prevents catastrophic battery degradation from overcharging or deep thermal runaway, resolves electrical transients and noise coupling common in dirty grid environments, and eliminates unnecessary field truck rolls through robust remote root-cause diagnostics and smart low-voltage disconnect (LLVD/BLVD) controls.
Who and where it is for
5G/4G outdoor macro base station enclosures, telecom central offices, edge computing data nodes, hybrid solar-diesel microgrid controllers, and trackside railway signaling DC backup plants.
Core advantages
- Dual isolated CAN and RS485 communication backplanes ensuring collision-free rectifier control and sensor telemetry.
- Comprehensive battery health algorithms supporting temperature compensation, programmable charge limiting, and smart multi-stage disconnect.
- Native industrial SNMP v1/v2c/v3, Web, and NetNumen protocol support for seamless third-party DCIM integration.
- True online hot-swappable architecture with non-disruptive parameter synchronization, yielding an MTTR of under 3 minutes.
