Uninterruptible Power Supplies PS

UPS ON LINE of PS series with the power output range from 1000VA up to 5000 VA are designed for an uninterruptible supply of computer systems and equipments with high demands on the input voltage quality and reliable operation. Optional accessories provided with the UPS are modules used for a communication with the supply system.

PS series are noted for a high stability of the output voltage 230 V ±1% at a mains input voltage floating and also at a load change. The UPS stabilizes the voltage and switches to the back-up mode in case of a mains failure or of a voltage drop below a limited level that depends on the connected load on the UPS output. The level of the mains input voltage is in the range of 99 V - 260 V.

The UPS was developed using high technologies and modern component base. The circuit solution is of an on-line type with a double conversion based on a pulse-width modulation with a high working frequency. This enables to reach a high level and a shape input voltage stability and an effective interference suppression. It is possible to connect an optional complete load with the power factor of 0,6 up to 1 to the output.

All important functions are controlled by a microprocessor. UPS are fitted with a built-in communication with the PC, a programmable switching-on/off, a possibility of configuration of some parametersdisconnect and they are fitted with BY-PASS.

Switching to the back-up mode is automatic with the transfer time of 0 seconds. The energy source in the back-up mode is a built-in, leaded, sealed, maintenance free battery. The back-up time depends on the size of the connected load and the number of connected external battery modules.

- when there si a higher number of battery modules, it is necessary to connect an external accumulator charger
- back-up time depends on used battery modules

Modules RP 215(R), RP 230(R)

The modules RP are a switching-over equipment, whose function is to ensure a co-operation of two supplying UPS which are connected in the MASTER (superior – the mains) - SLAVE (subordinate – the second supply that operates in case of a mains failure) hierarchy . The RP switches over the supplied equipment so that this switching-over is not registered at all and thereby it guarantees the system redundancy.

The HC20 module is designed to monitor back-up UPS by ELTECO, a.s. company on the serial RS 232/422/485 link and at the same time it is equipped with a status interface informing about basic statuses, in which the UPS is present.

The HC10 module is a programmable control unit designed for a remote control (start and switching off) of the genset, in dependence on the UPS status and on the input mains. The module is designed to be built-in into the UPS of PS normalised series, designed to be built-in into the 19" rack.

An acoustic module that signals by voice the UPS status, normally it is built-in in the PS 30-50N, as an optional accessory it can be built-in into the PS 10-20N.

These accessories can be requested directly when ordering the UPS or ordered additionally, the assembly is then realised by a service technician from ELTECO, a.s. company.
