Description
The QPX Series DC Power Supply is a powerful and flexible unit designed for lab benches and system racks. It offers a high power output (up to 1,200 W) and supports a wide range of voltage and current combinations — for example, up to 80 V and 50 A within the same power envelope.
What makes it special?
- It uses “PowerFlex” or “PowerFlex+” regulation, which means it gives you more current at lower voltages than a standard supply.
- You get very low noise and ripple — typically less than 3 mV rms at full power.
- The setting resolution is extremely fine — 1 mV on up-to-60 V ranges, allowing you to dial in precise voltage.
- It’s built for bench top or rack mounting, with output terminals both front and rear so you can set it up in many configurations.
- Remote control and automation are available on many models: USB, RS-232, LAN (LXI) and optional GPIB interfaces.
- It includes protections like over-voltage (OVP) and over-current (OCP) trips so you can test safely.
In simpler terms: If you’re working on advanced electronics, embedded systems, or test labs and need a supply that can handle high power, flexible voltage/current rails, and give you precise control and measurement — the QPX Series DC Power Supply is a top-solution.
