Material Composition: Outer housing: Cold‑rolled steel sheet with powder‑spray anti‑corrosion coating Internal circuit board: FR‑4 flame‑retardant circuit board Power‑output terminal: Copper alloy with tin‑plated anti‑oxidation treatment Internal power transformer: Silicon‑steel sheet laminated core

Structural Characteristics: Standard DIN‑rail snap‑in mounting structure on housing backplane Screw‑locking wiring terminals on front panel for input and output connection LED status indicator located on front‑panel surface Fully enclosed metal housing structure, internal natural convection air slots No built‑in fan, zero moving mechanical components

Working Principle: AC grid voltage enters internal rectifier‑filter circuit, converted to DC voltage. High‑frequency switching power conversion circuit outputs stabilized 24 V DC. Built‑in sampling circuit monitors output voltage and current in real‑time. When overvoltage, overcurrent or short‑circuit fault occurs, protection circuit cuts off power output automatically to protect post‑stage weighing control hardware. Power‑grid noise filter suppresses surge and interference signal from input side to guarantee high‑precision weighing signal stability.

Installation Requirements: Install inside industrial control cabinet on standard TS35 DIN rail. Maintain clearance space around unit for natural convection heat dissipation, do not stack other heat‑generating components closely adjacent. Input power wiring must match local AC voltage specification. Separate power‑supply wiring from weak‑signal weighing cable to avoid electromagnetic interference. Secure ground connection to cabinet protective ground busbar. Keep ambient operating temperature within 0 °C‑55 °C range, avoid direct sunlight radiation.

Usage Notes: Do not exceed rated maximum output current. Do not operate outside specified ambient temperature range. Cut off input power before wiring and maintenance. Do not open metal housing cover in powered‑on state. Avoid corrosive gas, dust and moisture accumulation inside control cabinet. When power supply triggers protection shutdown, remove short‑circuit or overload fault before restarting. Regularly inspect terminal screw tightening condition to prevent poor contact heating.
