Pyramid 13.8V 5A Linear Bench Power Supply

Designed for hobbyists, technicians and bench engineers, the PS7KX offers simple plug‑in operation and reliable DC power for testing radios, electronics projects, scanners and small devices. Its compact metal cabinet, integrated heatsink and cooling fan keep performance stable while screw terminals make hookup straightforward without extra adapters.

How does the PS7KX deliver steady power for my bench projects?

The PS7KX uses a linear regulated design to provide a constant DC voltage suitable for sensitive electronics. It maintains rated output under typical loads and gives a short surge capacity for temporary peaks.

• Continuous output: 5.0 amps at 13.8V DC
• Peak surge: up to 7.0 amps for brief demand spikes
• Input: 115V AC, 60Hz, 70W maximum power
• Linear regulation for low noise and stable voltage

What safety and protection features are built in?

This unit incorporates multiple safeguards to protect both the connected device and the power supply itself. Protective systems reduce the risk of damage from common electrical faults.

• Electronic overload and short‑circuit protection
• Fuse protected with auto‑reset for repeated fault tolerance
• Metal enclosure with heatsink surfaces to dissipate heat
• Cooling fan to manage operating temperature during continuous use

How do I connect devices and what types of equipment work with it?

The PS7KX uses color‑coded screw terminals for secure, hardwired connections without soldering or special plugs. It is suitable for a wide range of 12–14V DC devices commonly used in hobby and bench environments.

• Universal screw‑type terminals: red positive, black negative
• Ideal for CB radios, HAM gear, scanners, chargers and test circuits
• Tabletop placement with on/off switch for easy control
• Rugged construction for repeated use in workshops and labs

What are the physical size and installation considerations?

The supply’s compact footprint fits on a workbench or shelf without dominating space, and its solid build makes it suitable for stationary setups. Allow clearance for airflow around the fan and heatsink for optimal cooling.

• Dimensions: 7.5" L x 4.9" W x 3.0" H — small desktop profile
• Mount as a bench unit or inside an equipment rack with ventilation
• Screw terminal wiring requires basic hand tools and insulated leads
• Front power switch for easy on/off control

Who is this for: The Pyramid PS7KX is aimed at hobbyists, radio operators, DIY electronics builders and bench technicians who need a dependable, low‑noise DC source without complex setup. If you want an affordable, plug‑in linear supply with screw terminals, built‑in safety features and a compact footprint for everyday testing and small equipment powering, this unit is a practical choice.
