basler KR7FF voltage regulator avr 63 vdc KR7FFMM 7AMP
Freshly rebuilt tested and certified by FLIGHT SYSTEMS. COMES WITH 90 DAY WARRANTY AND FREE TECH SUPPORT. Basler KR7 7amp voltage regulator for medium to large generator requiring up to 7 amp excitation field. Lists for $3000 new. Voltage taps for different voltages.
The KR series of regulators provides field excitation voltages of 32, 63, and 125 Vdc for 50/60 Hz
generators to maintain the generator line voltage within a tight regulation band. Sensing voltage
selection is accomplished using easily accessible, Faston terminals.
All KR voltage regulators utilize thyristors in the power stage. They employ built-in electromagnetic
interference (EMI) suppression to reduce the conducted interference generated by the thyristors.
Figure 4 provides details on the levels of EMI suppression.
Selection of 50 Hz or 60 Hz underfrequency protection is easily accomplished through the use of
Faston terminals. *Although the underfrequency operational threshold is normally factory preset at
a nominal 6.0 Hz below the system frequency. The percentage of generator output voltage obtained
for a specific reduction in frequency is illustrated in Figures 2 and 3.
A full line of accessories is available for use with the KR regulators, enabling the user to meet other
system requirements including excitation support, paralleling, and manual voltage control. These
accessory items are described on page 3.
KR-FFMX: The KR-FFMX regulators are designed to operate in a high humidity environment.
Although similar to the KR-FF, the KR-FFMX utilizes hermetically sealed components, moisture
resistant sealed transformer, sealed potentiometers and urethane coated printed circuit board and
Regulation accuracy better than 1%.
Applicable to either 50 Hz or 60 Hz generators.
Built-in underfrequency protection for voltage regulator and generator system.
Moisture resistant (KR-FFMX only).
Adjustable stabilization network.
Externally adjustable voltage range.
Internal build-up circuits.
Solderless reconnectable Faston terminals facilitate selection of sensing voltage and frequency
Mechanically rugged, welded steel chassis.
Compact, reliable, economical.
Complete accessory line available.
