Frequently Asked Questions - PS8KX Pyramid

What is the input voltage for the Pyramid PS8KX?

The input voltage is 115 VAC (standard US household voltage). Plug into a 110V AC outlet.

How do I connect my device to the PS8KX?

Connect the power cord of your equipment (which requires 13.5V – 14.1VDC) to the binding post terminals on the front. Observe correct polarity: Red is positive (+), Black is negative (-). Reversing polarity may damage your equipment.

What is the maximum output current?

The maximum continuous current rating is 8A (as indicated by the model number PS8KX). Do not exceed this rating.

What does the overload protection do?

The unit has electronic overload protection with instant automatic reset. If the output is overloaded, the power shuts off automatically. Remove the load, check your equipment's power rating, and the unit will reset instantly.

How do I replace the fuse?

The fuse is located at the rear of the unit. Unscrew the fuse holder to access the fuse. For the PS8KX, use a 1.5A fuse. Do not use a larger fuse, as it may damage the unit.

Does the PS8KX have over-temperature protection?

Yes. The PS8KX includes over-temperature protection circuitry to prevent overheating. The unit will shut down after a minimum of 15 minutes at 100% rated load, or 25 minutes at 80% rated load.

Can I use the PS8KX outdoors?

No. Do not use outdoors or expose the unit to rain, moisture, water, or any other liquids.

What should I do if the unit consistently shuts down?

Consistent shutdown indicates you are drawing too much amperage. Return the unit to the place of purchase and upgrade to a model with higher amperage. Do not bypass or alter the protection circuit.

Can I open the case for repair?

No. Do not remove the cover under any circumstances. If the unit is damaged, return it to the dealer for service. High voltage inside – refer to a qualified technician.

What type of equipment can I power with the PS8KX?

The PS8KX provides a regulated DC output of 13.5V – 14.1V, suitable for equipment that requires this voltage range and draws up to 8A. Ensure your equipment's total amperage does not exceed the unit's rating.

CIRCUIT DIAGRAM PS-3KX/4KX/7KX/8KX

CIRCUIT ARE SUBJECT TO CHANGE WITHOUT NOTICE

OPERATION:

1 INSERT AC POWER PLUG INTO A 110V VOLT AC OUTLET.
2. CONNECT THE POWER CORD OF YOUR EQUIPMENT (13.5V — 14 1VDC) TO THE OUTPUT BINDING POST TERMINALS ON THE FRONT OF THE UNIT. BE SURE THAT POLARITY IS CORRECT. THE RED POSITIVE (+) TERMINAL AND BLACK NEGATIVE (-) TERMINAL ARE MARKED, REVERSAL OF POLARITY MAY DAMAGE YOUR EQUIPMENT.
3 TURN SWITCH TO "ON", RED LIGHT IN SWITCH WILL ILLUMINATE
4 THE INPUT POWER IS PROTECTED BY THE FUSE WHICH IS-LOCATED AT THE REAR OF THE UNIT AND CAN BE REPLACED BY UNSCREWING THE FUSE HOLDER IF THE FUSE IS BURNT OUT. DO NOT USE A FUSE LARGER THAN .. AMPS. USE OF HEAVIER FUSE MAY RESULT IN DAMAGING TO THIS UNIT .(.. SEE NOTE)
5. THIS UNIT HAS ELECTRONIC OVERLOAD PROTECTION WITH INSTANT AUTOMATIC RESET FUNCTION. IF OUTPUT IS OVERLOADED. THE OUTPUT POWER WILL AUTOMATICALLY SHUT OFF. RELEASE POWER CORD OF YOUR EQUIPMENT FROM THE OUTPUT TERMINALS AND CHECK THE ACTUAL POWER RATING OF YOUR EQUIPMENT. THIS UNIT WILL AUTOMATICALLY RESET INSTANTLY
6. OVER TEMPERATURE PROTECTION CIRCUITRY IS USED IN PS-7KX/8KX TO PREVENT OVER HEAT DAMAGE. UNIT WILL BE SHUT DOWN MINUTES AFTER 15 MINUTES(MIN.) AT 100% RATED LOAD. 25 MINUTES(MIN.) AT 80% RATED LOAD.

NOTE PS-3KX:1.5 AMP
PS-4KX : 1.0 AMP
PS-7KX : 1.5 AMP
PS-8KX : 1.5 AMP

CAUTIONS:

1. DO NOT USE WITH EQUIPMENT REQUIRING MORE THAN RATING AMPS.
   2- DO NOT USE OUTDOORS. DO NOT EXPOSE UNIT TO RAIN, MOISTURE, WATER OR ANY OTHER LIQUIDS
2. DO NOT REMOVE COVER IN ANY CASE. RETURN TO DEALER FOR REPAIR IF DAMAGED.
3. THIS UNIT HAS A SPECIAL BUILT-IN FEATURE THAT WILL SHUT THE UNIT DOWN IF MARKED AMPERAGE IS EXCEEDED. THIS WILL AVOID BURN-OUT OF YOUR EQUIPMENT AND OF UNIT. IF UNIT DOES CONSISTENTLY SHUTDOWN. THIS MEANS YOU ARE DRAWING TOO MUCH AMPERAGE. RETURN UNIT TO PLACE OF PURCHASE AND UPGRADE TO NEXT AVAILABLE UNIT OFFERING HIGHER AMPERAGE. PLEASE DO NOT BYPASS OR ALTER THIS CIRCUIT AS IT IS THERE TO PROTECT YOU. ANY ALTERATION OR MISUSE WILL VOID YOUR WARRANTY.
