Main Outputs; Specification - TTI TS Serie Anleitung

The Thandar 'S' series DC supplies are laboratory quality power supplies with remote sensing on all
outputs. The main outputs have dual 0.5" 3.5 digit liquid crystal displays which simultaneously display
output voltage and output current. With the output switch OFF the display can be used to preset the
output voltage and current limit prior to connection of the load. The outputs operate in constant current or
constant voltage mode with automatic cross-over; a display annunciator indicates constant current mode.
Coarse and fine controls permit the output voltage to be set within 5mV and the current limit control is
logarithmic to give good resolution at low current settings. Load and line regulation are better than 0.01
% with ripple and noise typically better than 1mV. Outputs can be switched to be independent or tracking
on those supplies provided with a tracking facility.
The logic supply output has a single 0.5" 3.5 digit liquid crystal display which displays either output
voltage with the output switch OFF or output current with the output switch ON. The output voltage is set
by a calibrated control and a display annunciator indicates current limit. Over-voltage protection is
provided. All outputs are protected against forward or reverse voltages. The power supplies have a steel
case, rubber feet and integral mains lead.
