The Multi Sentry 12kVA/10.8kW uninterruptible power supply from Critical Power Supplies is an on-line double-conversion UPS. The UPS has a three phase input and output. Typical applications: Blade servers, comms rooms, server rooms and datacentres.

Multi Sentry has a very high operating efficiency (94%), high input power factor, advanced battery management and can work in one of several operating modes: On-line, Economy, Smart active and Standby/Off, as well as operating as a frequency converter.

Features and Benefits.

Multi Sentry UPS have been designed for an easy install, especially on sites with limited power capacity available, a generator and harmonic compatibility problems. Typical features include:

- Low input current distortion – less than 3%
- High input power factor 0.9
- Power walk-in function to achieve progressive rectifier start-up
- Delayed start-up on mains power supply return
- Extended Runtime available upon request

The UPS also acts as a high performance filter to protect its supplies from load induced harmonics and reactive power.

Multi Sentry has a unique battery care system to optimise battery performance, extend working life and guarantee the UPS is fit to deliver its full-rated runtime when called upon to do so – in the event of a complete mains power failure. The UPS is designed to operate with a range of battery types: VRLA
AGM and GEL lead-acid batteries including open-vented types, in addition to Ni-Cads.

Specific Battery Care features include:

- One-level recharge to meet the requirements of the most common VRLA
AGM batteries.
- Two voltage level recharge meeting the IU characteristic.
- Restricted charging to reduce electrolyte consumption and extend the life of VRLA batteries.
- Temperature compensation: to avoid excessive voltage being applied to the batteries in a high ambient.
- Built-in battery testing to enable predicted failure reports and detect performance degradation.
- Deep battery discharge protection: to prevent over discharging the battery set.
- Low AC ripple current, achieved using a high-frequency battery charger.
- Wide input voltage range, with a rectifier that can work down to less than 40% of its nominal supply rating.

Multi Sentry can be used for a wide range of applications with several customisation options and accessories providing flexibility and a choice of performance levels:

- compatible with capacitive loads – without any reduction in active power (0.9 lead to 0.9 lag).
- multiple operating modes: On-Line, Eco, Smart-active and Stand-By/Off and frequency conversion.
- PowerShare connections for priority-based load shedding on mains power supply failure.
- cold-start facility to allow the UPS to be switched on even without a mains power supply present.
- extended runtime options using battery extension cabinets.
- battery cabinet temperature sensor option to assist the temperature compensating charger.
- larger battery charger options to optimize recharge times.
- dual input supplies options for added resilience.
- isolation transformer options for Galvanic isolation and neutral connectivity.

No matter what, your UPS, Generator, Cooling, Switchgear or Electrical Hardware must be ready to perform at all times. While every power solution we supply is backed-up by a comprehensive warranty with the manufacturer, maintenance plans to ensure business continuity are highly recommended, particularly for UPS systems from 1kVA. In particular, the battery set is of prime importance, and must be in good working order. With other consumables, such as fans and DC capacitors requiring regular maintenance and inspection logs reviewed to predict potential future problems.

4. IR Thermal Imaging Surveys - Infrared electrical inspection. Infrared electrical testing finds hot, dangerous problems quickly. Infrared electrical inspections find hot spots caused by defects in connections and components.

Detect system overloads, loose defective components and damaged switchgear. Infrared electrical testing finds hot, dangerous problems quickly. Infrared electrical inspections find hot spots caused by defects in connections and components.

Infrared thermography is used to find areas of excess heat (caused by increased resistance) so that problems can be corrected before a component fails, causing damage to the component, creating safety hazards and productivity loss. Because increased heating is a sign of failure, infrared is the best diagnostic tool available for finding these hot connections in the early stages of degeneration.
