The new PL and PL-P series advanced DC laboratory power supplies from T H U R L B Y T H A N D A R I N S T R U M E N T S offer linear regulation for optimum output noise and transient response, ultra compact dimensions for minimum bench or rack space, true analog controls for simplicity of operation, and advanced digitally based features such as V-Span and S-Lock. Remote control is possible using Analog, RS-232, USB, and LAN/LXI (PL-P series) interfaces.
The document introduces the new PL and PL-P series of linear laboratory power supplies, highlighting their analog controls, digital stability features such as S‑Lock and V‑Span, and compact high‑density design. It describes safety interlocks, remote control options (RS‑232, USB, LAN/LXI), and the various output configurations including dual‑output PL303QMD models.
Detailed specifications are provided for each model, including voltage and current ranges, power ratings, noise performance, regulation, and protection features. The brochure also lists mechanical dimensions, cooling methods, and environmental ratings, and ends with a selector table summarising the full product line.
| PL155 Maximum Power | 75 W |
|---|---|
| Output Noise (rms) | <0.4 mV |
| Line Regulation (Voltage) | <0.01 % + 2 mV for 10 % line change |
S‑Lock digitally locks voltage and current settings at the touch of a button, preventing accidental changes.
All operations that could change voltage or current unexpectedly are interlocked with the output switch to prevent accidental changes.
