Laboratory Grade & High RFI Immunity Switch Mode Power Supply with Rotary Encoder Control
1. INTRODUCTION
This series of efficient, state-of-the-art Switch Mode Power Supplies (SMPS) feature a small form factor, automatic
crossover between Constant Voltage (CV) and Constant Current (CC) modes, three voltage and current presets (for
quick access to frequently used settings), remote on/off and remote analogue control of both voltage and current. In
addition the HCS-310x, HCS-3150, HCS-320x and HCS-3x00-USB series have a USB port for control of the Power
Supply by computer using the supplied PC software or user-written application software under Windows, Linux or on
the Mac under OSX.
The power supplies also feature dual action (coarse/fine) rotary encoders with a micro-control unit (MCU) making
setting the voltage and current levels smooth, precise and quick. A new feature with this range of power supplies is the
precise setting of the current limit without requiring the output terminals to be short circuited.
The HCS series power supplies are suitable for a wide range of applications in the laboratory and in research, servicing,
telecommunications, production, field testing and in manual and automated control of a wide range of high power DC
devices.
2. WARNING
• Do not use the power supply near water.
• Do not operate or touch the power supply with wet hands.
• Do not open the casing of the power supply when it is connected to ac mains.
• Refer all servicing to qualified service personnel.
• Before replacing the AC fuse located at the AC mains input socket, rectify the cause first.
• Replace the AC fuse only with the same type and rating as the original.
• The maximum voltage of some models is over 60VDC. Avoid touching the output terminal metal contacts!
3. CAUTION
• Always use a grounded three pin (earthed) AC source.
• The unit is for indoor use only.
• Do not operate or place the unit in a humid, dusty, in direct sunlight location or near any heat source.
• Before plugging into the AC mains plug, check the rating label on the back of the unit.
• Do not block any ventilation openings or fan outlets on the unit
• The unit must be used within the specified rating. Exceeding the maximum voltage or current specification loading
may cause damage to the power supply.
• The gauge size of the input power cable must be at least 0.75mm
exceed 3m.
• Always use the supplied USB cable with ferrite core when using computer control. Always disconnect the USB
cable when not in use.
