OPTIONAL EQUIPMENT OVERVIEW
:
a.)
Uninterruptible Power System (UPS) Option
An optional UPS is offered for systems that need emergency back-up power. The
system can easily be connected to a battery for uninterruptible operation. Not only
does the power supply power the load, but it also charges the battery. If the AC
power fails, the battery will uphold the load. In the event that the batteries voltage
drops below a safe level, a Low Voltage Battery Disconnect (LVBD) module will
disconnect the battery from the load. This will protect the battery from completely
discharging and prolong the life of the battery. Batteries can be supplied upon
request or a conventional battery configuration can be used (See Figure 3).
Two TTL alarms are included: “AC Good” and “DC Power Good”. A TTL high is a
non-alarm condition and a TTL low is an alarm condition. An optional emergency
shut down pin is available.
b.) DC Input Power Option (S1)
The BDA is equipped with both AC and DC voltage inputs for power operation. This
gives the flexibility of powering the BDA with either an AC or DC source. If both
sources are connected, the BDA will automatically select the stronger source for
power.
