Basler Electric ES-37, Undercurrent Relay

ES-49 temperature relays use resistance detectors (RTDs) to monitor remote

temperatures. An ES-49 relay can be specified with three or six inputs and

specified to monitor copper or platinum RTDs. Microprocessor-based circuitry

enhances functionality and improves performance.

Internal diagnostics annunciate when relay function or accuracy is compromised.

ES frequency relays provide frequency monitoring and protection for use in

single-phase or three-phase applications. Three models are available: the

ES-81O provides overfrequency protection, the ES-81U provides underfrequency

protection, and the ES-81O/U provides overfrequency and underfrequency

protection. Microprocessor-based circuitry enhances functionality and improves

performance. Internal diagnostics annunciate when relay function or accuracy

is compromised.

The DECS-250 is a complete digital excitation control system.

Total control in a compact package provides precise voltage, var and power

factor regulation, and exceptional system response, plus generator and

motor protection. An optional power system stabilizer helps you meet

stringent grid code compliance requirements. The DECS-250 offers extreme

flexibility and total functionality in a cost effective, easy-to-use package.

Product Features & Benefits

• Reduce your setup time with Basler’s intuitive BESTCOMSPlus® software

that simplifies complex setup with simple drag-and-drop programmable logic,

visual real-time strip chart capabilities, and cutting edge auto PID selection

capabilities.

• The revolutionary auto-tuning function automatically establishes optimum

PID and gain settings, taking the guesswork out of system setup, reducing 

commissioning time and cost while maximizing overall system performance.

• Network Load Sharing provides easy implementation in complex paralleled

systems.

• The Offline Simulator in BESTlogic™Plus helps identify and troubleshoot the

logic without the expensive need for physical hardware.

• Powerful 15 amp pulse-width-modulated (PWM) power stage provides a

high initial response for exceptional system response to load transients.

Flexible PWM power stage makes it easily adaptable to any system – shunt,

auxiliary winding, permanent magnet, or dc fed.

• The DECS-250’s rms sensing and rugged power stage creates an easy,

worry-free solution for applications containing high waveform distortion

caused by non-linear loading.
