Power Inspired's New VFI-B Series of Uninterruptible Power Supply (UPS) provides best in class performance and power protection at a fraction of the prices of comparable systems. Providing protection against power failure, power sags, power surges, brownouts, line noise, high voltage spikes, frequency variations, switching transients and harmonic distortion, with features that include high output power factor, online double conversion technology, adjustable voltage, frequency conversion, hot swappable batteries, extended run and load shedding the VFI-B provides outstanding value for money. Take a look....
Modern electrical design standards now insist that equipment has as near as possible to unity input power factor, this renders the specifying of Volt-Amps meaningless in UPS. The VFI-B series high power factor ensures that it will be suitable for your load.
Voltage & Frequency Conversion: The true online double conversion technology will always provide a constant high quality voltage output regardless of what is happening to the input mains supply. This output can be adjusted to 208V, 220V, 230V or 240V depending upon your application. The unit auto senses the supply frequency and will output this as default (50Hz in Europe) however it can be configured to always be either 50 or 60Hz, allowing equipment designed for US 208V 60Hz supplies to be operated from the VFI3000B.
EPO: The VFI-B is fitted with an Emergency Power Off (EPO) terminal that will completely shut the unit down when activated allowing the UPS to be used in applications where power protection is required but with the ability to ensure load can be disconnected in an emergency. This EPO terminal can be configured for either normally open or normally closed operation.
Each Battery Module has its own built in charger, and does not rely upon the charger built in to the UPS. This mechanism ensures that the addition of battery modules does not impact the recharge time.
The battery modules are truly matching. Each is the same physical dimensions of the parent UPS.
With the VFI-B Series you can program a load segment to be shut down when the battery levels falls to a pre-defined state, keeping the more critical loads running for as long as possible.
The battery modules contain 2 packs and the replacement procedure is excatly the same.
In the event of a UPS fault, a code is provided to enable a quick lookup to determine if the fault may be a site issue, or if the fault can be addressed on site or a replacement is required.
An 'Intelligent Slot' is also provided for connection of either a Relay or SNMP Card. A relay card contains a set of contacts that activate when certain UPS events occur - such as on battery, low battery or fault. This can be connected to an external alarm panel either bespoke or part of a Building Management System, or to an AS400 type server.
An SNMP card provides the ability to monitor and control the UPS over a network and even remotely using the internet. Two types of card are available - basic performance and advanced. The advanced card is suitable where secure protocols such as SNMPv3 are required.
In ECO (economy) mode the UPS behaves like a line interactive UPS and will only activate the inverter when the mains supply is out of tolerance. However, with the VFI-B series the tolerance at which the unit will operate in ECO mode can be adjusted allowing savings in operating costs specific to your operating environment without compromising functionality.
