What are the mounting options for the charger?
The BC-2000 Charger can be mounted to the wall, on the floor, on a shelf, or on an EIA 19-inch or 23-inch rack (front or rear).
What kind of batteries are compatible to charge with the BC-2000?
The BC-2000 can charge batteries of a wide variety of types. These include Vented Lead-Acid (VLA), Valve Regulated Lead-Acid (VRLA), and Nickel-Cadmium (Ni-Cd).
What operating conditions should the charger be kept in?
The operating temperature range of the unit is -40 – 158ºF (-40 – 70ºC), and the operating humidity range is 0-95% relative humidity.
What method of cooling does the charger employ?
The BC-2500 was designed to stay cool by venting air using natural convection, which avoids potential electrical and safety issues which often arise when fans are used.
Can an iPM be replaced (hot swapped) while the charger is on?
Yes, the charger never needs to be powered down to replace an iPM.
Which components of the BC-2500 are microprocessor based?
All iPMs have microprocessors that interpret instructions from the UIM and then maintain those instructions as to how to care for the batteries. The UIM also has its own microprocessor for receiving and communicating instructions, as well as alarms. Since they all have their own processors that is what allows multiple failures in one chassis (including the UIM) and the charger will continue to provide DC voltage and current.
Is it possible to load share between multiple chargers?
The BC-2500 chargers will load share independently, no need for any special cables or added options. As one charger reaches capacity, another will ramp up quickly to support the incoming load. The BC-2500 chargers are highly filtered to operate as a DC power supply too, so they react extremely fast to load changes to support the load.
For the optional Alarm Relay System, how are the relay contacts wired?
The Alarm Relays have 3 points per alarm, Normally Open, Normally Closed and Common. This depends on the relay that the charger is connected to and what the relay requires. A common installation error is the wires get flipped by accident. If they are, no damage will occur.
For the optional Alarm Relay System, do the contacts change state when the system powers on/off?
It is critical that the user understands, if AC fails, the alarm board latches and continues functioning. The reason is if AC fails, you want those alarms to stay active and feedback to their SCADA/central operations as to what the state of the charger is currently. If AC returns, the alarms will expire if the values the charger is seeing are within the alarm trigger levels set on the webserver/dashboard. The alarms are self-clearing so if the event expires, the alarm goes away. In addition, every alarm is also recorded, and time/date stamped in the history records.
Where can the optional Alarm Relay System be mounted?
The remote alarm relay box can be mounted on a wall or near the charger if the cable will reach. Avoid mounting it to the side of chassis as a screw or bolt could contact the iPMs. The rack brackets offer a lot of places to anchor it to.
