Tailored solutions for diverse sectors and challenges.
These relays provide accurate and reliable percentage-differential protection for power transformers against internal faults.
The SCP 250 controls generator or motor power factor or vars by monitoring the voltage and current and supplying a control input to a voltage regulator.

For those control systems requiring remote or multi-point adjustment of regulators, governors, and other devices, Basler Electric manufactures the MOC-2 series of motor operated controls. Control switches are available for “Raise-Off-Lower” control and are listed in Regulator Accessories Price List.
The MOC series of motor operated controls consists of a motor-driven, variable potentiometer and the limit switches required to provide remote adjustment of resistance or voltage. MOC2XXX controls can be specified for ac or dc operation with 24-, 32-, 48-, or 120-volt control power.
The EL200 series minimum/maximum excitation limiter imposes limits on the solid-state voltage regulator to prevent insufficient or excessive values of exciter field current. This device helps assure safe generator operation.
The EDM200 module is a device added to the exciter field circuit to monitor the output of the brushless exciter power semiconductors. The EDM200 is compatible with all phase fired Basler Voltage Regulators. Operating Power – Voltage Input: 100-120, 200-240, 380-480, 528-600 – 10VA – 50-60 Hz. Frequency Exciter Field Current Sensing – 0-7 Amperes or 0-100 mV
