Flow

& Operati

Sequences

Figure 4.1

Input power: Provides the AC power needed for the UPS rectifier circuit and charger.

UPS input isolation transformer: This is an optional purchase equipment; its goal is to isolate system power in order

to avoid affecting the input main power due to UPS abnormalities.

UPS rectifier input EMI Filter: Suppresses the electromagnetic interference signals at the power side or UPS rectifier

input side.

Backfeed relay for the UPS input terminal: Safety relay; the backfeed relay is opened during DC mode to prevent

dangerous voltage from remaining at the input terminal.

UPS rectifier input fuse: Provides over-current protection for the UPS rectifier circuit.

PFC rectifier: Converts the AC voltage to DC voltage when the main power is normal, and corrects the power factor

of the input AC power.

Inverter generator: Converts the DC voltage to AC voltage.

Output relay: Used as the switch between inverter and bypass; the UPS will automatically switch the output from the

inverter to bypass output when there’s an overload or when there’s UPS abnormality.

UPS output EMI Filter: Suppresses the electromagnetic interference signal at the UPS output side to avoid mutual

interference between the load and UPS.

UPS output power: Provides stable AC power needed for the load.

Charger: Charging device for the battery.

Booster: Boosts the battery voltage to the DC voltage needed by the inverter when the main power is abnormal.

External battery module: External battery modules can be added when longer backup power time is needed.

Battery input fuse: Protects the battery when the DC booster circuit malfunctions.

Communication interface: Includes 1 RS-232, 1 optional USB and 1 optional slot (shared with a set of RS-232).

Communication expansion slot: Provides a hot-swappable slot for the optional interface card; provides development

and application for diverse needs.

Optional interface cards: Includes SNMP card, dry contact card, RS-232 card and USB card.
