BSFC-02C BSFC-12C charging controllers
Product description
ACS880 frame size R8i inverter modules can be connected to the drive DC bus through a disconnector (or fuse-switch). This configuration requires a charging circuit to charge the DC capacitors of the modules in a controlled way. The DC voltage can be directly connected to the modules only after the capacitors are charged to a sufficient level. The BSFC is a unit that monitors the charging, and controls switch-on and switch-off of the DC voltage.
In addition to inverter units, the BSFC can be used with other units consisting of R8i modules, such as brake or DC/DC converter units. One BFSC unit can control the charging of up to 3 frame R8i modules.
The BSFC unit can be installed onto a standard mounting rail.

Application field
User turns charging switch [Q10] to position 1 (ON).
• Charging of the inverter capacitors starts through the charging resistors [R10]:
• Auxiliary contact 1-2 of charging switch [Q10] opens.
• BSFC prevents the starting of inverters and the closing of DC switch-disconnector [Q11].
• BSFC monitors inverter UDC signals through fiber optic link(s) INV1…INV3.
• INV STAT and PWR LEDs are on.
• When the charging is complete (inverter DC voltage over 80% of nominal):
• BSFC receives a UDC signal from the inverter(s).
• BSFC connects operating voltage to the solenoid of DC switch-disconnector [Q11]. The solenoid releases the locking mechanism, allowing operation of the handle.
• INV UDC and PWR LEDs are on.
• The Charging OK light [P11] on the cabinet door is on, indicating that the operation of the DC switch-disconnector [Q11] is allowed.
2. User turns DC switch-disconnector [Q11] to position 1 (ON).
• Main contacts 1-2…7-8 of DC switch-disconnector [Q11] connect inverter(s) to DC power supply.
• Auxiliary contact 13-14 of DC switch-disconnector [Q11] closes.
• Auxiliary contact 21-22 of DC switch-disconnector [Q11] opens, de-energizing the solenoid. The Charging OK light [P11] on the cabinet door goes off.
• INV UDC and PWR LEDs are on.
3. User turns charging switch [Q10] to position 0 (OFF).
• BSFC receives a “main switch ON, charging switch OFF” signal through terminal AUX2.
• BSFC sends an enable signal to inverter through the fiber optic link.
• INV UDC and PWR LEDs are on.
