Functional Features: Universal wide‑range AC input adapts to variable industrial‑site power‑supply fluctuation; built‑in EMI filter suppresses power‑line surge and high‑frequency noise interference; front‑panel potentiometer realizes DC24 V output voltage fine adjustment; hardware over‑current protection with auto‑recovery characteristic; green LED indicator directly reflects real‑time output power‑on status; compact DIN‑rail mounting structure saves control‑cabinet installation space.
Application Scenarios: Industrial control cabinet internal DC24 V auxiliary power supply; power supply for PLC, proximity sensors, photoelectric sensors and intermediate relays; legacy automation cabinet power‑supply unit replacement; small‑scale automation equipment DC power distribution.
Performance Parameters: Typical power conversion efficiency reaches above 80%; mean time between failure MTBF reaches 135000 hours under standard operating condition; vibration and shock resistance comply with DIN‑rail industrial component standards; supports continuous 24‑hour cabinet‑internal operation within rated load range.
Material Composition: Light‑gray V0 flame‑retardant engineering‑plastic housing; internal FR‑4 power‑grade multilayer glass‑fiber printed‑circuit board; high‑efficiency switching power electronic components; EMI filter inductor and capacitor assembly; brass nickel‑plated finger‑safe screw‑type terminal blocks; green high‑brightness power‑status LED indicator; metal spring‑loaded DIN‑rail mounting buckle.
Structural Features: Rectangular compact DIN‑rail module profile; rear‑side integrated spring‑type DIN‑rail buckle for fast cabinet installation; front‑panel arranged AC input terminals, DC output terminals, voltage‑adjustment potentiometer and power‑status LED indicator; top housing surface equipped with slotted ventilation grille for natural convection heat dissipation; finger‑safe terminal cover prevents accidental human contact with live terminals.
Working Principle: External AC mains voltage connects to input screw terminals, passes through built‑in EMI filter circuit to eliminate power‑line interference. Then alternating current goes through rectifier circuit and switching converter circuit to generate stabilized DC24 V output voltage. Internal current‑detection circuit monitors output current continuously. When over‑current fault appears, over‑current protection activates to limit output current, and power supply will auto‑recover after fault load removes. Front‑panel potentiometer changes reference voltage to realize fine adjustment of DC output voltage. Green LED illuminates when normal DC output voltage exists.
Installation Requirements: Secure S82K‑05024 onto standard cabinet 35 mm DIN rail; do not block top‑surface ventilation grilles, reserve adequate surrounding heat‑dissipation clearance; select input and output cables with sufficient conductor cross‑section according to rated current; separate AC input power cables from weak‑current signal cables; implement reliable protective grounding for control cabinet.
Usage Notes: Total connected load power shall never exceed 50 W rated output capacity; implement power‑derating operation when ambient temperature exceeds 40 °C; hot‑wiring operation under powered‑on state is strictly forbidden; this model does not support parallel operation for power capacity expansion; do not deploy in environments with condensation, conductive dust or corrosive gas; regularly inspect screw‑terminal fastening torque.
