Description
Metso D200136
Technical Specifications Input voltage 115 / 230 V AC auto-ranging; input frequency 50 / 60 Hz; output 28 V DC; rated output current 9 A; operating ambient temperature -20 ℃ to +70 ℃; rack plug-in form factor; protection rating IP20 for cabinet installation; built-in overvoltage, overcurrent and overtemperature shutdown protection; CE and UL certification.
Functional Features Automatic AC voltage range detection; internal power factor correction circuit; continuous DC output regulation; front panel power and fault LED indicators; fast shutdown when internal fault detected; backplane power distribution to all modules in rack; input surge suppression for industrial power grid disturbance.
Application Scenarios Pulp and paper mill DCS control cabinets, mineral crushing and flotation plant control racks, metal processing plant automation systems, legacy Metso MAX control system retrofit and spare replacement.
Material Composition Flame-retardant plastic module housing; high-density FR4 power PCB with power switching semiconductors; aluminium heat sink for power device cooling; gold-plated backplane edge connector; screw terminal blocks for AC mains input; metal shielding can for switching noise suppression.
Structural Characteristics Horizontal rack plug-in module; front panel fitted with status LEDs and AC input terminal block; rear gold finger connector mates with Metso MAX rack backplane; internal layout separates high-voltage AC primary circuit and low-voltage DC secondary bus; heat sink aligned with cabinet airflow path.
Working Principle AC mains voltage enters module input terminals. Rectifier and switching converter convert AC to regulated 28 V DC. Output power feeds rack backplane bus to supply all installed control modules. Protection circuits monitor output voltage, output current and internal temperature. Any parameter exceeding threshold triggers power shutdown and illuminates fault LED.
Installation Requirements Insert module only into de-energised Metso MAX rack; connect protective earth terminal to cabinet earth bar; verify mains voltage matches auto-range capability; maintain cabinet forced convection airflow to satisfy thermal limit; secure terminal block screws firmly.
Operation Notes Wait for internal bus capacitors to discharge before removal; inspect input fuse rating before replacement; do not operate module outside specified temperature range; use D200136L variant for high-humidity or corrosive cabinet environments.
