NP-9615 SERIES DC REGULATED POWER SUPPLY

USER’S MANUAL

INTRODUCTION

The NP-9615 series DC regulated power supply is a compact, well regulated laboratory style unit. It is suitable for
service work, hobby and educational use as well as laboratory use in many fields of science and engineering. It
provides one variable output and two fixed outputs for a wide variety of applications.

Please read these instructions carefully and follow them to prevent abuse or misuse of the power supply. These
instructions must be kept for future reference.

FEATURES

1. Overload and short-circuit protection: when the unit detects an overload or a short-circuit condition the

output current is limited to that set.

2. Independent 5V and 12V outputs with easy snap-on output terminals. These voltage outputs are ideal for

TTL or CMOS circuit testing. As the outputs are not grounded, they can provide negative voltages or can be
wired in series for a higher output voltage (17V).

11. Power Cord 12. Fan Outlet

INSTALLATION

1. Ensure that the AC supply power is ±5% of the rated input voltage. Also ensure that the unit is properly

grounded through the AC mains plug.

2. DO NOT place the unit in dusty or highly humid locations. DO NOT place the unit in direct sun-light or

locations subjected to high temperatures.

3. Place the unit in a location which provides unobstructed air circulation.

4. The unit is for Indoor Use Only.

CAUTION

1. DO NOT use the unit for powering devices that require higher current than the maximum - otherwise

damage may occur to the unit.

2. DO NOT replace the fuse and operate the unit before rectifying the problem that caused it to fail. Always

replace the fuse with the same rated type. Always unplug the unit before attempting to replace the fuse.

3. If the external power cable or cord of this unit is damaged, it must be replaced by the same or equivalent

unit from the manufacturer or service agent. The supply cord and plug must be installed and protected in
accordance with national wiring rules.

SAFETY PRECAUTIONS

1. NEVER remove the metal cover of the power supply with the AC power connected. Allow the unit to cool

before opening the cover. Some components may burn your hand in the event of a component failure. Only
qualified personal should open the cover.

2. NEVER touch the unit with wet hands or allow it to become wet.

3. NEVER operate the unit if foreign materials such as metallic objects, liquids or other debris have fallen inside.

Return to the manufacturer or dealer for checking and repair.

4. NEVER operate the unit if it has been damaged. The voltage regulation circuitry may have been disabled,

resulting in high voltage and damage to your equipment.

5. NEVER allow foreign objects to come into connect with the DC output terminals.

6. NEVER block the vents - including the cooling fan outlet.

7. ONLY connect to the AC mains outlet when in use, at all other times disconnect the power supply from the AC

mains outlet.

CONNECTION AND OPERATION

1. Make sure the input AC power source is as per the label before plugging in the unit.

2. Turn ON the power supply and adjust the output voltage to match that of your equipment. Adjust the

current limit to that required. Then turn OFF the power.

3. Connect your equipment to the unit. Positive polarity to red (+) and negative polarity to black (-).

4. When ready, turn ON the power supply and then turn ON your equipment.

5. When finished, turn OFF your equipment and then turn OFF the power supply.
