PRODUCTS UPS & STANDBY POWER REMOTE MONITORING OF BACK-UP POWER


Cummins Power Generation has launched a new web-based means of remotely monitoring and controlling on-site generator sets, transfer switches, sensors and output controls from any PC or Mac computer. The new PowerCommand 500/550 Remote Monitoring System enables multiple authorised users to remotely determine the status of annunciators, alternators, engines and transfer switches from anywhere, reducing the need for costly service calls and site visits. With the PowerCommand system, users can remotely start and stop generators, start and stop transfer switch tests, and reset and acknowledge faults.


Well suited for a range of on-site power applications such as data centres, health care, manufacturing,


offices and schools, the system is available in two levels of capability. The PowerCommand 500 remote monitoring system is capable of monitoring and controlling two devices, such as one generator set and one transfer switch in a typical standby power application. The PowerCommand 550 remote monitoring system is capable of monitoring and controlling up to 12 on-site devices, such as multiple generator sets, multiple transfer switches or other I/O modules. Both remote monitoring systems are compatible with power generation equipment from Cummins Power Generation as well as third party manufacturers.

Caterpillar has introduced two new 50Hz extensions to its diesel generator sets, specifically configured to offer fuel efficient power nodes that address the growing demand for back-up power in emerging markets. The Cat 3516C-HD diesel generator set is rated at


2,750kVA (2,200ekW) for standby and mission critical applications, while the Cat C32 diesel generator set is available in a 1,250kVA (1,000ekW) power rating for standby and mission critical needs. Both generator sets are optimised to minimise fuel costs, reduce lube oil consumption and extend the time between overhauls. “Emerging economies are growing and


becoming increasingly complex, but in many cases the power grid is not maturing quickly enough to consistently support the critical operations that are fueling economic growth,” said John Swanson, marketing division manager for Caterpillar Electric Power Division. “These two new power nodes offer reliable sources of back-up power in packages specially designed for the rapidly growing needs of emerging markets.” Both generator sets are configured with the Cat


SR5 generator, which is precisely matched to the performance and output characteristics of Cat engines. The Cat 3516C-HD and Cat C32 diesel generator sets have an air-to-air aftercooler


(ATAAC) cooling system with a radiator core design that condenses the footprint, improves airflow, increases static restriction capability and lowers transportation costs. This radiator package delivers an ambient capability of 50°C. These new generator sets are engineered to ISO


8528-5 transient response requirements, accepting 100% rated load in one step. To read the full story visit

A FOCUS ON PROTECTION


Unveiled at this year’s Counter Terror Expo in April, Harland Simon UPS’s new ProtectUPS is designed and manufactured to provide uninterrupted power to support critical applications in harsh conditions and to help guard against key threats to Critical National Infrastructure (CNI) in line with the Security and Emergency Measures Direction (SEMD). In addition to the core product offering, visitors to the Harland stand had the


opportunity to select a bespoke product specifically designed and installed to a variety of specifications available i.e. WIMES (water), MILSTAN/DEFSTAN, IACS-E10 (marine), LUL and Network Rail. The Harland ProtectUPS incorporates features and modifications using rugged, commercially available


modules and components that are supported worldwide and designed to be fully field replaceable with readily available form-fit-function alternatives.

The new Qunit AC UPS from Phoenix Contact includes IQ technology which achieves high system availability for loads with 120 or 230V AC and 500VA power. A pure sine curve is available for the output voltage, so that even sensitive loads can be operated without interference on networks from 80-264V AC. The power supply is already


integrated in the housing. Power storage rounds it off and converts it into an intelligent UPS solution. As such, the load is consistently supplied during mains operation as well as in the event of mains failure. The offline UPS is combined with


power storage in VRLA technology with 3.4 to 38Ah. For a longer service life and buffer times of up to 45 minutes at 15W power, the power storage with lithium- ion technology is well suited. The UPS- CAP power storage devices with maintenance-free dual layer capacitors achieve a maximum service life of over 20 years at ambient temperatures of -40°C to 60°C. With VRLA-WTR batteries, buffer times of two hours at 400W power or 40 hours at 15W power can be achieved. The IQ technology communicates


with the power storage and determines all relevant states such as voltage or temperature. This transparency ensures the reliability of the UPS and the optimum use of the battery. The battery management detects the current charging state of the connected power storage device and uses this to calculate the remaining run-time. The remaining life expectancy of the battery is also known. Gaps in supply and premature shutdown of industrial PCs are completely avoided. The information provided by the UPS


can be forwarded to higher level controllers via Ethernet or be implemented directly in control solutions from Phoenix Contact. Status information from the control system logic is available centrally there, so that the system can respond with a program routine in specific situations.
