OVERVIEW
The Thurlby-Thandar TSX series represents the state of the art in high output PSU design. A wide range of voltage-current output combinations will become available with power levels of 360 Watts and more.
The standard versions
The standard TSX versions of the series incorporate conventional analogue controls for precision with simplicity. Large diameter knobs and large paddle switches combine with the big bright displays to provide simple and unambiguous control.Coarse and fine voltage controls offer fast setting with high setting resolution at all levels while a semi-logarithmic current control provides resolution commensurate with the current level. These PSUs are ideally suited to general purpose applications in many technology areas.
Linear post regulation for unrivalled performance
The heart of all TSX series PSUs is an innovative regulator design which combines switch mode pre-regulation with linear post-regulation. The pre-regulator uses specially developed techniques to dramatically reduce the capacitance between input and output thus eliminating the high levels of common-mode noise normally associated with switch mode PSUs. The linear post-regulator combines very low levels of output noise with excellent load regulation and transient response. The result is performance comparable with a pure linear design.
Compact and lightweight
The hybrid regulator design provides a PSU which is both smaller and lighter than competitive products.
The high thermal efficiency also means that the PSUs are silent in operation since fan cooling is unnecessary.
Bench or rack mounting
The attractively styled casing takes up very little bench space and incorporates a tilt bail to angle the front panel when required.
The case is half rack width (3U height), an optional rack-mount kit is available.
Output terminals are fitted at both front and rear.
* Note that in rack environments with limited ventilation fan cooling may become necessary.
Constant voltage or constant current operation
All TSX series PSUs can operate in both constant voltage and constant current modes with automatic crossover and automatic mode indication.
High accuracy metering
All versions incorporate high resolution digital meters for both voltage and current.
V and I levels can be set to high accuracy prior to connection to the load and the limit settings can be checked at any time.
A damping switch for the current meter enables the average value of rapidly changing currents to be read.
Full overvoltage protection
All versions incorporate a fully variable OVP trip to protect against regulator failure.
The output is fully protected and other protection functions include regulator overtemperature, and sense miswiring.
