Single 0-250V/0-0.375A Higher Voltage Linear Regulated DC Bench Power Supply

The PLH Series is the latest high-performance linear regulated DC power supply range from TTi. It is based on the New PL Series of lower voltage precision linear power supplies (which offers up to 60V) and has an identical casing style and similar power output. However, certain features relevant to the higher voltage are different.

The PLH Series has true analog controls but combines them with new digitally based convenience features.

TTi PLH Series: 120V & 250V Linear Regulated Laboratory Power Supplies

Higher Voltages Without Lower Performance

The PLH series is a development of the best-selling New PL series of laboratory bench power supplies which is available in 15V, 30V and 60V variants (covered in a separate brochure and on our web site).

The PLH series retains the ultra compact format, high power density, and smart analog controls of the PL series but offers voltages up to 250V to cover applications beyond the capabilities of standard bench PSUs and into areas such as magnetics.

TTi has been at the forefront of laboratory power supply design for around thirty years during which it has re-defined the state-of-the-art for switch mode products with its innovative Mixed-mode and PowerFlex regulator designs. Demand for linear regulated PSUs has remained strong and continuing development of linear models has generated the lower cost ELR series, and the advanced QL series in addition to the ever popular PL series. The PLH and PLH-P series of linear regulated higher voltage DC power supplies joins a large family of PSUs with power levels from 15 watts up to 1200 watts.

Analog Controls with Digital Stability

As technology has changed, many products have moved from analog controls to digital ones. Although digital controls suit many instruments, they do not necessarily suit a bench power supply. Customer research shows that many users prefer the speed and simplicity of conventional analog controls for setting voltage and current. Digital controls may offer greater precision, but often at the expense of ease-of-use. With this in mind, the New PL series has retained the true analog controls of its predecessor.

The main disadvantage of analog controls is stability and security. The settings of analog potentiometers can drift over time. More importantly, the settings can be changed accidentally with potentially serious consequences.
