Basler Electric Negative Sequence Voltage Relay BE1-47N STYLE E3FD1PD2N4F

The BE1-47N Voltage Phase Sequence Relay provides protection for rotating equipment

from the damaging effects of excessive negative sequence voltage resulting from phase

failure, phase unbalance and reversed phase sequence.

Basler Electric offers a high powered, low-cost digital excitation control system,

the DECS-100. This environmentally rugged product is ideally suited for

controlling the output of brushless excited synchronous generators up to 5MW.

The DECS-100 has a very impressive 7Adc output from a pulse width modulated

power stage. The DECS-100 is perfect for machines that will be paralleled to other

generators and/or to the utility system. It is ideal for distributed generation,

co-generation and peak shaving applications. 

The DECS-100 is easy to use, and it has communications capability with a PC.

The DECS-100 utilizes microprocessor technology and control algorithms pioneered

by Basler Electric for longer than a decade. It shares many features and functions

of our larger excitation control systems.

The DECS-100 is Basler Electric's fifth generation of microprocessor-based excitation

system.

The Electronic Manual Voltage Control MVC-300 is a solid-state device en

closed by a wrap-around metal chassis. The MVC-300 is for mounting through

a panel with controls accessible from the front of the panel or can be mounted

behind the panel. A terminal strip located on the rear of the device facilitates

installation. A manual voltage adjust potentiometer and a manual-off-auto

switch are provided on the front face of the unit. For use of a user-supplied

external manual adjust potentiometer or for adjust by a motor operated control

(MOC), order MVC-301. The MVC-300 and MVC-301 are designed to operate

with Basler voltage regulators powered from 120 or 240 volt AC sources up to

320 Hz. The adjustable output of the MVC-300 supplies power to 32. 63 or 125

volt fields at 7 amps.

Engine Protection and Metering

Engine protection features include oil pressure and coolant temperature

monitoring, overcrank protection, ECU-specific protection elements,

and diagnostic reporting.

Metered engine parameters include oil pressure, coolant temperature,

battery voltage, speed, fuel level, engine load, coolant level (from ECU),

ECU-specific parameters, and run-time statistics.
