Description
Metso D200136L
Technical Specifications Input voltage 115 / 230 V AC auto-ranging; input frequency 50 / 60 Hz; regulated output 28 V DC, 9 A maximum output current; operating ambient temperature -20 ℃ to +70 ℃; PCB with full conformal coating; rack plug-in compatible with Metso MAX rack backplane; overvoltage, overcurrent and overtemperature protection; CE, UL and RoHS compliance.
Functional Features Conformal coating prevents circuit corrosion and condensation leakage; retains all power regulation and fault protection functions of D200136; front panel visual status indication for power normal and fault condition; surge suppression for industrial AC input transients; continuous DC bus supply for rack I/O and controller hardware.
Application Scenarios Pulp mill wet-end control cabinets, offshore mineral processing auxiliary control racks, chemical plant corrosive atmosphere control rooms, high-humidity wastewater treatment DCS racks.
Material Composition Flame-retardant plastic housing; FR4 power PCB coated with acrylic conformal coating; aluminium alloy heat sink; switching power semiconductor devices; gold-plated backplane connector; surge suppression components; anti-corrosion treated terminal hardware.
Structural Characteristics Rack plug-in mechanical footprint identical to D200136; front panel status LED array; rear edge connector compatible with same Metso MAX rack backplane; coated PCB assembly sealed against airborne contaminants while maintaining thermal dissipation path.
Working Principle Power conversion sequence matches D200136. AC input converts to regulated 28 V DC for rack backplane. Conformal coating provides dielectric protection for PCB traces and components when ambient humidity rises or corrosive vapour enters cabinet. Protection circuits activate to shut down power on overcurrent, overvoltage or over-temperature events.
Installation Requirements Install in ventilated electrical cabinet; connect protective earth to cabinet ground bus; confirm rack backplane compatibility with Metso MAX series; route AC input cable with adequate current rating; maintain minimum clearance for heat convection around module.
Operation Notes Do not scrape conformal coating during handling or maintenance; avoid solvent contact with coated PCB surface; use this L suffix model instead of D200136 for pulp and corrosive plant locations; test fault indication function after installation.
