Basler Electric BE1-25A - Manual (Page 16)

SPECIFICATIONS
General specifications for the BE1-25A system are provided in the following paragraphs. For
specifications that apply only to particular options, see the ensuing subsection entitled Specifications of
Options.
Voltage Sensing Inputs 70 to 150 Vac, 50/60 Hz. Burden: Less than 6 VA for the generator
(Bus and Generator) input; less than 2 VA for the bus input.
Contact Sensing Inputs Requires a user-supplied contact with a minimum rating of 0.05 A at
250 Vdc.
Power Supply Power for the internal circuitry may be derived from 90 to 132 Vac at
50/60 Hz (single phase), or 70 to 150 Vdc. Burden: Less than 20.0
VA.
Outputs Output contacts are rated as follows:
Breaker Closing
Normally open. Make and carry 30 A at 250 Vdc for 1 second, 7 A
continuously, and break 0.3 A at 250 Vdc. (L/R = 0.04).
Voltage, Frequency (Speed) Correction, and Lockout
Form C (SPDT). Make and break 5 A at 250 Vac (80% PF), 5 A at 28
Vdc (resistive), and 0.5 A at 120 Vdc (resistive).
Tolerances
Advance Angle The command for breaker closure occurs within
±3.0° of phase
coincidence of bus and generator. (Closure will not occur if the
calculated advance angle exceeds 40
°.)
Lockout Occurs when breaker reopens within 15
±10% seconds after the
initiation of breaker closure.
Slip Frequency ( F
S
)
±0.001 Hz
Generator Undervoltage
±1.0 V
Inhibit
Control Ranges The following parameters are settable over the indicated ranges.
MAX SLIP Adjustable from 0.01 to 0.500 in steps of 0.001.
BRKR TIME The characteristic breaker time settings are adjustable from 0.02 to
0.8 seconds.
Generator Undervoltage Adjustable from 40 to 110 Vac.
Inhibit
NOTE
When a sync output closure is initiated, the sync output contact will be held
closed for the duration of the Breaker Operating Time setting (or 250 ms
minimum).
