Aim-TTi (TTi) High Power Compact Bench Switch Mode PSUs

<p>The <strong>EX series</strong> of switch mode PSUs provide high levels of power at a very affordable price. By combining switch-mode pre-regulation with linear post-regulation, performance levels comparable to an all linear design have been achieved.</p>
  • Single, dual and triple output models
  • Power from 175W to 420W
  • Voltage from 18V to150V
  • Compact design takes up minimal bench space
  • Quiet operation
  • Mixed-mode regulation
  • Excellent line and load regulation
  • Low Noise
  • Good transient response
  • High power efficiency
  • Constant voltage and constant current modes with automatic crossover
  • Coarse and fine voltage control
  • Logarithmic current control enabling low currents to be accurately set
  • Separate digital voltmeter and ammeter for each main output
  • Current limit settings are displayed when output switch is off, enabling verification of settings
  • Bright LED display with 14mm high characters and an update rate of four per second
  • All outputs short circuit proof and fully protected against external voltages and reverse currents
  • EX-R models feature remote sensing
  • EX355P model features an RS-232 interface to give a basic programmable PSU
  • Complies with EN61010-1 and EN61326
  • Aim-TTi EX series
