About the TSX3510
The TSX3510 is a single-output bench DC power supply from Thurlby Thandar Instruments (now Aim-TTi), adjustable from 0 to 35 V at 0 to 10 A.
It uses mixed-mode regulation (switch-mode combined with linear) for high efficiency, low noise (typically under 1 mV rms) and a fast transient response, and it is cooled by convection without a fan. Voltage is set with coarse and fine knobs to within 10 mV, and current with a semi-logarithmic knob. The output switches between constant voltage and constant current automatically. Two 4-digit LED meters show voltage and current, and the panel has buttons to read the OVP level, check the V/I settings and damp the current meter.
Protection covers over-voltage trip (adjustable 10-110% of full scale), regulator over-temperature and sense miswiring. Remote sense is on rear screw terminals. The steel case is half rack width and 3U high, and a rack kit is available. This unit is the analogue TSX (Series I) version; the TSX3510P is the programmable model, and Aim-TTi replaced Series I with the nearly identical Series II in 2017.
Frequently asked questions
Is the TSX3510 programmable?
No. The TSX3510 has analogue front-panel controls and no remote interface. The TSX3510P is the programmable version.
How does it differ from the TSX1820?
Same case, controls and features. The TSX3510 gives 0-35 V at up to 10 A, and the TSX1820 gives 0-18 V at up to 20 A.
Which version is this, Series I or Series II?
Series I. Aim-TTi says Series II replaced it in 2017 and is nearly identical; Series I has 4 mm binding posts on the front and a mains voltage selector on the rear, while Series II has shrouded safety terminals.
Does it need a fan or forced cooling?
No. It is convection cooled and runs silently.
