TTi launches PL-P(G) Series of power supplies

TTi has introduced the PL-P(G) Series of ultra-compact linear-regulated power supplies, incorporating five types of remote-control interfaces.

The interfaces include GPIB, USB, RS232, Ethernet (LXI) and analogue.

USB and RS232 are most likely to be used for small systems or single PC control, while GPIB and LXI are more appropriate for larger system use.

GPIB (IEEE-488) is widely used for instrument systems.

However, the company claims that LAN-based systems are becoming increasingly popular because of their simple and low-cost cabling and the elimination of the need for a dedicated controller interface.

LXI (LAN extensions for instrumentation) is the LAN-based equivalent to GPIB, combining the advantages of Ethernet with the simplicity and familiarity of GPIB.

The PL-P(G) Series conforms with LXI 1.2 (category C) and includes a built-in web server that provides information, configuration and control via a web browser.

The interfaces provide full control and read-back with a setting resolution of 1mV or 0.01mA.

Near-perfect load regulation can be achieved using the remote-sense terminals, which are fitted to both the front and the rear of the power supply, according to TTi.

The command set is compatible with a number of other TTi power supplies, including the QL and the original PL-P Series.

An IVI driver provides support for common high-level applications, such as National Instruments's Labview or Labwindows and HP/Agilent VEE.

The analogue interface enables the power supplies to be used in linear feedback systems as well as enabling automatic tracking of multiple units connected in parallel.

The company claims that the power supplies are linear regulated and offer a very low output noise combined with an excellent dynamic response.

They are compact, featuring 1/4 rack width (10 mm) and 3U height (131 mm).

Four units can, therefore, be fitted into a single rack width.

High thermal efficiency enables an unusually high power density to be achieved for a linear power supply, according to TTi.

Single-output models provide up to 90W, while dual-output units provide up to 180W.

Models are currently available with voltage ranges of 0-15V, 0-30V and 0-60V.
