Model HModel H
Introduction
The HP-460 Switching Mode DC Power Supply provides 60A of high power output, and
boasts of its small size and lightweight. It is especially suitable for high power radio as well
as high power linear power amplifiers working from DC 13.8V. Output voltage is variable
from 1V to 15V under 60A continuous operation.
Please read this instruction manual carefully and follow the instructions to prevent from
abuse or misuse. Keep the manual for your reference.
Features
1. Lightweight and Small Size
Switching mode power supply has the advantages of lightweight and small size. Comparing
with linear mode power with the same power output, it is much lighter and smaller in size.
2. High Efficiency
Total efficiency is 82% or higher under the best condition.
3. Overload Protection
The current foldback circuitry is employed to prevent from overload failures. The overload
indicator will light when the unit is overloaded.
4. Over Temperature Protection
The over temperature protection is triggered when the unit is over a certain high
temperature to prevent the unit from damage due to high temperature. When the protection
is triggered, the output voltage and current will decrease to a safety value and the overload
indicator will light.
5. High Stability for RF Stray
The protective circuitry against RF stray is incorporated for a most stable operation.
6. Variable Voltage Output
The variable range of output voltages from 1V to 15V is great for universal applications.
7. Multiple DC Output Connections
The unit has 5A auxiliary output terminal on front and full power screw-on output terminal at
rear.

Installation
1. Ground the unit to prevent from electric shock at high voltage caused by leakage or
⑪
lightning. (See
GND of illustration.)
2. Keep the unit in a cool dry environment, out of direct sunlight.
3. Allow some free space at both sides of cabinet, and never block the air intake window.
Otherwise air cooling will not work.
4. Never place the unit close to the TV sets or CRT monitor.
5. Plug into wall AC outlet directly, as source via distribution cables may heat plugs and
cable.
6. Put the unit horizontally for accurate meter readings.
Caution
1. Never exceed the designed output current limit of 60A. Otherwise it may damage the
unit.
2. Never use the unit for the lamps or motorized equipment, which require high current
input at starting and it may damage the unit.
3. Never replace the fuse before correcting problems and the correct value of fuse must be
put in place.
Safety Precautions
Read the following precautions carefully to prevent from electric shock.
1. NEVER remove the metal cover of the power supply while AC power is connected.
2. NEVER touch the unit when your hands are wet.
3. NEVER operate the unit if foreign materials such as metallic objects, water, or other
debris have fallen inside. Contact your dealer for repair and maintenance.
4. NEVER operate the failed unit, as the voltage regulation circuitry may have been
disabled. The resulting high voltage could damage your radio equipment.
5. NEVER allow foreign objects to touch the DC Power Output Terminals.
6. If you need to check the inside of the unit, cool off completely, as some heated
components may burn your hand.

Connection and Operation
Remote sensing wire should be at least 22AWG.
1. Connect the power supply to the AC Mains using the provided power cord.
2. Turn ON the unit and adjust the output voltage to match with the input voltage of the
objective equipment. Then turn OFF the unit.
3. Connect the equipment to the unit. Red (+) is connected to the positive polarity input of
the equipment and Black (-) is connected to the negative polarity input of the equipment.
4. Using the REMOT E SENSING feature:
Warning! Never short the Remote Sensing Terminal
You can use this feature to compensate the voltage drop of the long output line losses.
Connect the remote sensing terminal to the equipment’s input terminals as below:
5. First turn ON the unit and then turn ON the equipment.
6. When an operation is finished, turn OFF the equipment first and then turn OFF the unit.
