E20
Standardized range of industrial duty UPS systems suitable for use with 120V DC and 240V DC battery bus voltages. This product uses a sectional design for rectifier, inverter and bypass, a bypass transformer and regulating transformer can be easily added. Digital metering is integral with the status indicating mimic panel, supplementary analogue metering is available. Outputs from 7.5kVA to 150kVA with single phase 230V or 120V 50Hz or 60Hz.

CEG Series
Custom engineered grade (CEG), modular or sectional design concept of industrial UPS systems and inverters, with 120V DC and 240V DC battery bus voltages manufactured under a joint venture facility in Italy. This rugged and
custom engineered grade product is provided with analogue multi function metering and separate power flow status and alarm mimic panel, these products are intended for use in the oil, gas, petrochemical and other process engineering, power station and defence type applications. Outputs from 5kVA to 150kVA single phase with 230V or 120V output, also available with three phase output from 10kVA to 400kVA 50Hz or 60Hz, this product can also be supplied for frequency conversion applications.

Miniverter
19’’ rack mounting, heavy duty, rugged, seismically qualified UPS systems and inverters with single phase outputs up to 2000VA. Integrated and separate bypass modules and modular rectifiers are available and the product can be used with 48V DC or 24V DC station batteries. Miniverter rack mounting commercial class UPS systems are also available up to 5kVA complete with bypass and battery modules.

EF20
This range of industrial grade UPS systems is available with single phase input and single phase output in sizes up to 25kVA, an alternative version with three phase input is also available. The use of high frequency pulse width modulation (PWM) inverters ensures exceptional performance and extremely quiet operation. An important feature of this product is the automatic input power factor correction and harmonic compensation technique built into the rectifier, thus the total harmonic distortion reflected into the input power source is very low and the current consumption is optimised.

RTC20
Industrial grade compact, fully configured integrated style of UPS systems available with 6 pulse or 12 pulse rectifiers, manufactured under licence available in single module and multi module parallel configuration for installation in computer room or plant room. The inverter design is a high frequency PWM type with shielded logic, output isolation transformer, static interrupter with static transfer and manual bypass switch, a status indicating and alarm mimic with digital metering is fitted as standard. This product design has adopted the commercial standard DC bus voltage of 384 and can be used with all types of batteries, the VRLA batteries are supplied in enclosures to match the UPS enclosure. Available in sizes, 10kVA to 150kVA with single phase output and 10kVA to 350kVA with 3 phase output. The RTC range of products can also be supplied with 60Hz output or as frequency converters.

S10
Single phase output standard class UPS systems in capacities 7.5kVA to 25kVA with 3 phase input with limited integral battery space in the smaller sizes, suitable for all types of computer installation where this type of product is preferred to the more common ‘compacted’ commercial products. Available in single or dual module configurations.

S40
3 phase input 3 phase output fully configured standard class of UPS systems complete with static bypass, manual bypass and with limited integral battery space up to 30kVA. The range is from 10kVA to 200kVA in compact dimensions, low audible noise, high efficiency and available in single module or multi module parallel configurations.
