Alinco DM-33OMV Switching Mode DC Regulated Power Supply
Thank you for purchasing the Alinco switching mode DC-regulated power supply, DM-330MV. The DM-330MV instruction manual contains important safety and operating instructions. Read this manual carefully before using this product. Keep the manual for future reference.
INTRODUCTION
Alinco’s DM-330MV is a high-efficiency, compact, lightweight, high-performance switching mode power supply. It is also engineered to minimize the switching noise specifically for communication use. Even when noise occurs, it may be eliminated with the Noise-Offset function. Also convenient functions like pre- set voltage. remote control and a highly visible backlit meter are standard in this power supply.
CAUTION
- Even though the chassis of the unit is negatively grounded, use the correct term- minerals to connect the cable.
- When plugging the unit into a wall, it must be turned off.
- Place the unit in a dry and well-ventilated area.
- Never touch the unit while in use. Even though it is designed for high efficiency, the unit will still get hot.
- If the unit reaches- es a certain temperature, the “extreme temperature protection” function will protect the unit by automatically dropping– ping the current down to a safe level and the protection indicator will light up.
- A current limiting system will protect the unit from overloading. If a short circuit occurs at the output, the unit is protected by a short-circuit protection function.
- Immediately turn off the unit and repair the cause of the short circuit, then turn it back on.
- Do not use the unit for devices that require high current input at the start, such as motorized equipment. Do not use the unit to charge a car battery.
- Do not use a car cigarette lighter in the cigarette plug socket on the unit.
- Before replacing a fuse make sure the unit is turned off. Be sure to use the specified type of fuse.
- Make sure the product is always suitably grounded to prevent electric shock and to reduce noise. (The unit can be grounded by connecting a grounding cable to the appropriate screw).
- Never disassemble, modify, ör touch the inside of the unit unnecessarily.
- This could cause damage to the product and will void the warranty.
PRESET FUNCTION
When this function is activated, a preset voltage will be supplied regardless of the current voltage setting. To store the preset voltage, turn the switch to the preset position and adjust the preset voltage to the desired output level. When this function is selected the vol- The stage adjustment control on the front panel will be deactivated to protect from overvoltage.

REMOTE CONTROLLER
The DM-330MV does not include a remote controller. Nor is it available as an
optional accessory. It can be easily assembled using the diagram provided. The
adjustable voltage ranges from approximately 5~15 volts.
CAUTION
The remote controller must be assembled exactly as the diagram shows. Using SP
resistors of different values can damage the unit and will void the warranty.
When the remote controller is connected, the unit must be turned off. The
maximum length of cable. that should be used is 1.5m or 5ft.
PART NAMES AND FUNCTIONS
-
