Compact bench power supply provides 175W
The EX355, new from TTi (Thurlby Thandar Instruments), is a single-output laboratory DC power supply providing an output from 0 to 35V at 0 to 5A.
Programmable power-supplies offer outputs to 1kW
The XHR range of programmable power supplies, offering output ratings up to 1 kW is power-factor corrected for low current draw and reduced generation of input current harmonics.
Setting resolutions of 1mV and 0.1mA are provided, and output ripple and noise are below 0.35mV peak-to-peak.
Single and triple-output models are available with output voltages up to 56V and output currents up to 5A.
Maximum power is more than 100W per main output.
Good line and load regulation is matched with rapid recovery from transients.
Remote sense terminals are provided for optimum regulation at the load.
Local or remote sensing can be selected at the touch of a button.
Each model is available, optionally, with a full complement of bus interfaces that include RS232, GPIB, and USB.
The user interface has been designed to provide rapid control while guarding against any possibility of mistakes.
The QL series provides both numeric and rotary control.
Direct numeric entry provides a fast and safe method for entering precise values with the new setting being previewed before it is confirmed.
For applications where the voltage or current must be gradually changed, the rotary control allows settings to be incremented or decremented in a variety of step sizes.
The QL series has ten non-volatile memories per output for rapid recall of settings.
Stored values are previewed on the display before being confirmed.
A further power-down memory ensures that all settings are restored when the unit is powered back on.
User settable overvoltage and overcurrent trips are included.
An isolated output is provided on the rear panel for direct control of other equipment.
Automatic shutdown is implemented for overheating through blocked ventilation, regulator failure, or incorrect sense-lead wiring.
The QL series is suitable for bench use or rack mounting.
Rear terminals are provided for rack mounting, and up to three single output units can be mounted in the optional rack mount.
