Option Description
BPSU672
Strata CTX670 cabinet power supply must be ordered for each cabinet. Operates with 120VAC,
208VAC, or 240VAC connected as the system’s primary AC power source. It automatically
detects and adjusts to the type of primary AC power that is connected. The power supply is
included with each cabinet ordered but must be installed in the field.
Standard 9 ft. AC power cords with AC120VAC/15A plugs are provided with Strata CTX Base or
Expansion cabinets. When AC208V or AC240V power is used, a special AC cord, BACL240, is
required for each cabinet power supply and must be ordered separately.
RPSB2
Cabinet power strip for 120VAC primary power – provides three standard 120VAC/15A outlets
(NEMA5-15R) and nine ft. AC power cord with standard 120VAC/15A plug (NEMA5-15P). This
unit is field installed inside system cabinet side panels. The system can use 12 amps. (max.).
One RPSB2 is required for two cabinet systems if the local electric code allows only one AC
power cord to be connected to the system.
If the local electric code allows only one AC power cord to be connected to the system, 208VAC
or 240VAC must be used as primary AC power for systems with four or more cabinets.
One RPSB2 is required for a three or four cabinet system if the local electric code allows two AC
power cords connected to the system.
Two RPSB2s are required for a five cabinet system if the local electric code allows two AC
power cords connected to the system.
BPSB240
Cabinet power strip for 208VAC or 240VAC primary power - provides three 240VAC/20A outlets
(NEMA 6-20R) and 9ft. AC power cord with a standard 240VAC/20A plug (NEMA 6-20P). This
unit is field installed inside system cabinet side panels. The system can use 16 amps. (max.).
One BPSB240 is required for two or three cabinet systems.
Two BPSB240s are required for four or five cabinet systems.
Local electric codes allow only one AC power cord to be connected to the system when using
208VAC or 240VAC as the primary AC power.
BPSB240 conforms to the National Electric Code standards. If using 208VAC as primary power,
the plug on the BPSB240 AC power cord that exits the cabinet (NEMA 6-20P) may have to be
changed to a twist-lock type by a certified electrician to conform with local electric codes.
BACL240
AC208V or AC240VAC nine ft. power supply cord. The cord is rated at 10 amps. (max.) and
must be used when the system is powered by 208VAC or 240VAC. One cord is required for
each cabinet power supply and must be ordered separately only if using 208VAC or 240VAC as
the system primary AC power.
The cord is equipped with a 250VAC/20A plug (NEMA 6-20P) which is standard for 240VAC. If
using 208VAC as the system primary power this cord may have to be changed by a certified
electrician for one or two cabinet installations. If using three or more cabinets, a BPSB240
power strip is required and the power strip plug may have to be changed by a certified
electrician depending on local electric codes.
PBTC-3M
A three-meter long battery cable is used to connect reserve power batteries to the system
power supply when the system has less than three cabinets. One reserve power cable is
required for each cabinet in a one or two cabinet system (wall or floor mount). The cable
connects the Strata CTX670 cabinet power supply directly to the battery terminals (a BBDB is
not required).
