Product Introduction
ABB 216NG63 is an auxiliary power supply module. In order to supply the electronic units with power, the protection must be connected to an external auxiliary d.c. Supply (station battery). The auxiliary d.c. Supply unit 216NG61, 216NG62, or 216NG63 (DC/DC converters) steps the station battery voltage down to 24 V and provides electrical insulation between input and output voltages. The 24 V supply is distributed to the units inserted in the protection equipment rack via the B448C parallel bus.

Product Details
Auxiliary d.c. supply units 216NG61, 216NG62 and 216NG63：
The 216NG6. Auxiliary d.c. Supply unit transforms the station battery voltage UB to 24 V d.c. and provides electrical insulation between I/P and O/P. The technical data are given in the data sheet. Depending on the station battery voltage UB, one of the following types is installed:
216NG61 : for UB = 48 / 60 V DC ± 25 %,
i.e. 36...75 V DC
216NG62 : for UB = 110 / 125 V DC ± 25 %,
i.e. 82.5...156 V DC
216NG63 : for UB = 220 / 250 V DC ± 25 %,
i.e. 165...312.5 V DC
Frontplate signals and controls：
LED "U IN" (green): Lights when the I/P voltage (station battery voltage UB) is available.
LED "U OUT" (green): Lights when the O/P voltage (24 V DC before the plug-in jumpers A and B) is available.
Both LEDs "U IN" and "U OUT" must be lit during normal operation, i.e., when the protection is online and functioning.
Switch "I/O": Main ON/OFF switch for the auxiliary d.c. Supply unit.
I: ON
O: OFF
"24 V failure" signal
The failure of the 24 V output voltage is signalled on the front of the unit concerned by the LED "U OUT".
The failure of the 24 V output voltage is signalled remotely in three ways：
a) By auxiliary signalling relay K100 in 216NG6. K100 is continuously energised in normal operation, i.e., when the 216NG6. It is switched on and resets in the event of a failure of the 24 V output voltage.
b) By the standby signal line (bus conductor) CK. CK is at logical "1" during normal operation (O/P CHO02 energised). O/P CHO02 resets in the event of a failure of the 24 V output voltage. Note: If two 216NG6. Auxiliary supply units are installed in an equipment rack, and the jumpers are set for redundant supply; the failure of the 24 V output voltage of just one of the units is not signaled by the CK bus conductor.
c) In the event of an auxiliary supply failure, the first binary O/P unit energises the SML "System defect" signal line on the B448 parallel bus. This is signalled remotely via channel CHO01.
The auxiliary supply is switched off using a switch on the auxiliary d.c. supply units 216NG61, resp. 216NG62 or 216NG63. The following must be noted in this respect:
Every electronic equipment rack is equipped with its auxiliary power supply unit.
Either one or a maximum of two redundant 216NG6. Auxiliary d.c. Supply units can be installed in an equipment rack.
Where two redundant auxiliary d.c. Supply units are fitted; both units must be switched off.
Any work carried out on the protection, such as internal adjustments, inserting soldered jumpers, wiring, connections, etc., may only be performed by suitably qualified personnel. In addition to these instructions, all applicable local regulations governing work and safety must be strictly observed when installing, wiring, and commissioning the protection. Modifications and repairs to the electronic units or software changes may not be performed by the user. No liability will be accepted, and any warranty becomes invalid in the case of improper interference or tampering with the protection equipment. Defective units must be returned to ABB for repair.
