UPS systems in the Cayman Islands
If you want to protect valuable equipment and data from power fluctuations and power loss, you need an uninterruptable power supply (UPS). Corporate Electric can supply, install and maintain UPS equipment in sizes suitable for the small home user up to the largest full-scale network systems.
A UPS provides emergency power to a load when the input power supply fails. A UPS will provide near-instantaneous protection from power interruptions by supplying energy stored in batteries. Whilst the run-time of most UPS systems is relatively short, it is sufficient to start a standby generator and/or to shut down the protected equipment properly.
A UPS is typically used to protect hardware such as, computers, data centers, telecommunication equipment, process control instrumentation or other electrical equipment where an unexpected power disruption could cause injuries, fatalities, serious business disruption or data loss. UPS units range in size from units designed to protect a single computer to large units powering entire data centers or buildings.
Corporate Electric can provide:
- An on-site assessment
- Design to suit your budget and specific needs
- Installation with warranty
- Start up
- UPS service contracts
There are three main types of UPS equipment:
- An on-line UPS uses a “double conversion” technique by accepting AC input, rectifying this to produce DC for passing through the rechargeable batteries, and then inverting the DC back to AC for powering the protected equipment. There is no transfer or switching time since power flows through the battery system. By isolating the input from the output, on-line UPSs provide true sine-wave power free of any power anomalies.
- A line-interactive UPS maintains the inverter in the power supply line. Battery power is redirected from the normal charging mode to supplying current when power is lost. Line-interactive UPSs provide automatic voltage regulation when low or high voltage conditions occur, provide protection from voltage spikes and surges, and provide filtering from radiofrequency and electromagnetic interference.
- With a standby (“off-line”) system the load is powered directly by the input power, with filtering to protect from spikes and surges. In the event of a low/high voltage or blackout condition, the inverter switches to use battery power. The backup power circuitry is only invoked when the utility power fails.
UPS units are also capable of correcting common utility power problems:
- Voltage spike or sustained overvoltage;
- Momentary or sustained reduction in input voltage;
- Noise (defined as a high frequency transient or oscillation, usually injected into the line by nearby equipment);
- Instability of the mains frequency;
- Harmonic distortion (i.e. departure from the ideal sinusoidal waveform in the power supply).
We also offer a competitively-priced preventative maintenance program to undertake periodic inspection and tests to verify that the UPS equipment will operate reliably when required.
