250W DC/DC Converter

Syscal R2 | Elrec T
Brochure (PDF)

The Syscal R2 or Elrec T can be used with an external Direct Current (DC) power supply such as the 250W DC/DC Converter to inject energy into the ground.

Description:

The unit can be supplied by a 10 to 20V DC voltage source, for example a standard 12V car battery. It is protected against polarity inversion of input voltage and will stop operating when input voltages are greater than 20V.

Four output voltages (100V, 200V, 400V, 800V) can be selected through a manual switch. The maximum power available on each position is 250W, corresponding respectively to maximum intensities of 2500, 1250, 625 and 312mA.

The Converter has an internal warning signal to warn when the battery voltage is lower than 10V. When the input voltage is lower than 7.5V, beeping is continuous but the converter still provides a voltage. When the voltage is lower than 5V, the converter can not operate.

For each voltage position, two operating zones can be distinguished.

For higher load resistance, the unit operates as a voltage regulated supply, and the intensity of current is determined by the relation I = U / R;
For lower load resistance, the unit operates as an intensity regulated supply: the intensity of current is constant, whatever the resistance is, even in the short circuit case.

The intersection of both previous operating zones corresponds to the maximum output power of the unit (250W)
