Higher Current, High Power
The 400 Watt EX2020R combines high frequency switch-mode pre-regulation with linear post-regulation. This excellent line and load regulation is matched by low noise and good transient response.
The EX2020R has fan-assisted cooling that utilizes a low-noise brushless DC fan with intelligent control.
The EX2020R incorporates separate voltage and current meters on each main output with a fixed 10mA resolution, which avoids reading misinterpretation.
The EX2020R's output incorporates remote sense terminals that can easily switch to enable/disable.
Constant Voltage or Constant Current
The output of the EX2020R can operate in constant voltage or constant current mode with automatic crossover and mode indication. Course and fine voltage controls are provided. The current control is logarithmic, enabling low current levels to be set accurately.
Safety Binding-post Terminals
The EX2020R is fitted with TTi-designed output terminals that accept a 4mm safety plug with rigid insulating sleeve. These terminals also accept fork connectors or bare wires, giving maximum connection flexibility.
