Operating Instructions 1.0 General The range of REOTRON MEW Thyristor Regulators are microprocessor based units for controlling the power to resistive and inductive loads. In essence the units comprise inverse parallel connected power semiconductors (thyristors) and the control and regulation electronics. The units have a regulated, AC output. -
Page 5: Effective Current Value
ELEKTRONIK ELEKTRONIK ELEKTRONIK ELEKTRONIK REOTRON MEW Operating Instructions 2.1 Effective Current Value The effective current value is measured inside the unit through a current transformer and a burden resistor. The internal microprocessor determines the effective value of the output current and adjusts this using a PI regulator. -
