A Uninterruptible Power Supply (UPS), also known as an Uninterruptible Power Source, Uninterruptible Power System, Continuous Power Supply (CPS) or a battery backup is a device which maintains a continuous supply of electric power to connected equipment by supplying power from a separate source when utility power is not available. There are three distinct types of UPS: off-line, line-interactive (also called on-line) and double conversion (also called true on-line).

Harmonic Mitigation Transformers

Synergy Energy - Harmonic Mitigation Transformers

Application of these transformers facilitates compliance with IEEE-519 in commercial and industrial facilities. The Harmonic Mitigating Transformers treats all the tripplen harmonics (3rd, 9th, ….) through secondary flux cancellation. Unlike delta-wye transformers, in the T1000, 3rd and other zero sequence currents do not couple into the primary winding. 5th and 7th harmonics are treated on a system basis by alternating phase shifted models in a facility.

Hi-Efficiency Transformers

Synergy Energy - High Effeciency Transformers

Transformers designed to eliminate electricity waste in all applications “Green Transformer”. In addition to surpassing the minimum requirements of EPACT2005 it offers the lowest life cycle cost, contributes additional energy savings toward LEED and contributes to lowering greenhouse gas emissions.

Power Distrubution Modules

Cyberex - Static Transfer Switches

Large industrial units are used for taking high voltage and amperage and reducing it to more common and useful levels, for example from 220V, 30A, single phase to multiple 110V, 15A, or 110V, 20A, plugs. They are used in computer data centers, call centers, stage shows and in other electrically intensive applications. Some have features like remote monitoring or control down to the individual plug level. A PDU allows for a solidly bonded neutral, and a safe grounding system.

Branch circuit monitor for data centers

Branch Circuit Monitor

A branch circuit monitor includes a plurality of non-contact current sensors arranged to sense current on each of a plurality of branch circuits, the non-contact current sensors being connected to a common digital signal processor (DSP) module having as inputs the outputs of the current sensors and also voltage inputs from each power source. Data from the digital signal processor may be made available via communications protocols such as Modbus RTU or RS232/RS485/422, to any number of remote sites.

Automatic Transfer Switches

Transfer switches allow switching from a primary power source to a secondary or tertiary power source and are employed in some electrical power distribution systems. Most often transfer switches can be seen where emergency power generators are used to back up power from the utility source. The transfer switch allows switching from utility power to emergency generator power. The switch is either a manual switch, an automatic switch or a combination of manual and automatic. During a power outage, the transfer switches isolate the emergency circuits from the utility line allowing for efficient operation of the generator without back feeding onto the utility.

Data center emergency standby switch gear

Emergency/Standby Switch Gear

Many businesses go to staggering lengths to ensure 100% uptime, designing and building mission critical facilities to protect sensitive computer and telecommunications equipment from surges, spikes, brownouts, or other power quality problems that could corrupt data or destroy sensitive electronics. It is for mission-critical facilities such as these that Intellivex provides the highest quality, most dependable emergency and standby power control systems.

DC Power Systems

A rectifier is an electrical device that converts alternating current to direct current (converting AC to ADC), a process known as rectification. Rectifiers are used as components of power supplies, battery chargers, telecom facilities and as detectors of radio signals. A circuit which performs the opposite function (converting DC to AC) is known as an inverter.

AC Power / Inverter Systems

An inverter is an electronic circuit that converts direct current (DC) to alternating current (AC). Inverters are used in a wide range of applications, from small switching power supplies in computers, to large electric utility applications that transport bulk power.

Transient Voltage Surge Suppression (TVSS)

A surge protector is an appliance designed to protect electrical devices from voltage spikes. A surge protector attempts to regulate the voltage supplied to an electric device by either blocking or by diverting (shorting) to ground voltages that are above a safe threshold (voltage spikes).

Data center static transfer switch

Static Transfer Switches

A Static Transfer Switch provides break-before-make switching between two independent AC power sources for uniterrupted power to sensitive electronic equipment. When used with redundant AC power sources, the switch permits maintenance without shutting down critical equipment. The switch utilizes solid-state switching devices close to the critical load, thus producing high levels of power availability and power system tolerance. It is available in 100-4,000 A models. The switch is suited for data processing, distributed computing, telecommunications equipment, and high-tech manufacturing applications.
