Description
Emerson TREXCHPKLWS1
Technical Specifications: Input voltage: 100 VAC to 240 VAC Output charging voltage: 5 VDC Charging current: 1.5 A Operating temperature: 0 ℃ to 40 ℃ Storage temperature: -20 ℃ to 60 ℃ Relative humidity: 5% to 90% non-condensing
Functional Features: Wide range global AC input. Built-in battery overcharge, over-discharge and short-circuit protection. LED indicator shows charging and fully charged status. Compact portable design. Compatible with Trex communicator battery pack. EMC anti-interference design.
Application Scenarios: Field instrument maintenance workshop, DCS control room, petrochemical site instrument calibration, power plant transmitter maintenance, pharmaceutical factory instrument debugging, pulp and paper plant field instrument service.
Performance Parameters: Charging conversion efficiency: greater than 82% MTBF value: 185000 hours
Material Composition: Charger housing uses UL94-V0 flame-retardant thermoplastic. Internal PCB uses FR-4 glass fiber epoxy substrate. Power cable insulation uses PVC material. Connector contact pieces use nickel-plated brass.
Structural Features: Compact desktop charger structure. LED indicator on front panel. DC output port connects Trex communicator or battery adapter. AC input port connects mains power cable. Internal circuit integrates charging management chip and protection components.
Working Principle: AC mains power enters the charger. Internal rectifier and power conversion circuit convert AC to stable DC charging power. Charging management chip controls charging current and voltage. When battery reaches full charge, the circuit automatically stops charging to prevent overcharge. LED indicator changes state to show charging completion.
Installation Requirements: Place charger on flat stable desktop. Connect AC power cable to mains socket. Connect DC output cable to Trex communicator or battery adapter. Keep ventilation space around charger.
Precautions for Use: Use only for Emerson Trex communicator battery charging. Do not use in explosive hazardous area. Keep charger away from liquid and moisture. Unplug power cable when not in use. Stop using immediately if shell has damage.
