INTRODUCTION
The cooling capacities of the compressors are approx. 480 Watt (BD250GH.2) and 900 Watt
(BD350GH) @ Pe/Pc ~+15/+55°C
The system is able to operate in ambient temperatures up to +55 ºC (131 F).
The operating conditions are High Back Pressure (HBP).
The main functions of the controllers are:
• Motor / Compressor speed control
• Thermostat control (ON / OFF or electronic via NTC temperature sensor)
• ECO function to optimize compressor speed for minimum power consumption
• Condenser fan control
• Evaporator fan control
• Communication interface
• Monitoring function
• Error & event log
• Battery protection functions
• Main Switch
• Log of specific parameters
• Optimization of specific parameters via PC software before commencing mass production
The controller can be accessed using either
• The Secop software tool, Tool4Cool
®
LabEdition, or
• A custom interface. Please contact Secop for further information regarding custom interfaces.
The BD 48 V DC compressor systems are intended mainly for shelter cooling and cooling of bat-
teries in radio stations for cellular phones.
Secondary applications could be
• Spot cooling in golf carts, forklifts, etc
• Air cargo cooling
