SPH IND series represents the last transformer double conversion (VFI) power protection technology designed to protect a wide area of critical applications including server rooms, networks, telecommunication system, industrial processes and medical equipment. Unmatched reliability, excellent electrical performance, exceptionally compact size and outstanding cost-efficiency housed in an attractive enclosure are only some features of this new UPS solution.
Monitoring and control data are shown on an easy to understand front panel display featuring pushbutton controls, LCD read out for event logs and diagnostics and a mimic diagram for system status. The power protection system can be remotely monitored via RS232, RS485, dry contact or SNMP interface. The SPH IND series is available from 10kVA to 100kVA models.


The backup series is composed by: Rectifier, Inverter with transformer, Static Switch, manual by-pass and Battery.
The Rectifier-Inverter line normally feeds the users, and the Battery is kept charged by the Rectifier.
If a black out occurs, the Battery supplies power energy to users always through the Inverter. When the blackout is over, the Rectifier provides for Battery charge.
If a short circuit or an overload occurs to the users, the Static By-pass switches the load over the emergency line. When the fault is over, the Inverter feeds users.

The control panel consists of a graphic display, 6 LEDs of visual signal and 4 function keys. 5.1” LCD Display with 16 lines and up to 40 characters each. The resolution is 240×128 pixels in black and white.

Messages are available in the following languages: Italian, English, French, German, Spanish, Polish, Chinese, and Russian. A large graphic display is located at the center of the control panel, enabling you to always have a detailed overview of UPS status in the foreground and in real time. Directly from the control panel, the user can turn on / off the UPS, check the electrical measurements of the network, output, battery, etc., and perform the main machine settings.

The front panel (behind the door) allows access to the following communication ports:

  • Serial port, available with RS232 connector and USB connector.
  • EPO
  • No. 2 Expansion Slots for additional interface cards.

Dry contact card
There are two accessory types of dry contact cards, with 4 and 8-way programmable.

Emergency Power Off – EPO
The isolated contact is used to turn off the UPS in an emergency. The Emergency Power Off facility must use a Normally Closed contact, which opens to operate the emergency stop sequence. The EPO circuit is self-powered with SELV circuits. No external power supply is required.

The SNMP network adapter manages UPS through the LAN by using one of the main TCP/IP, HTTP, HTTPS, and SNMP v1 and SNMP v3 network communication protocols. The software allows UPS to be integrated into medium and large networks and to provide reliable communication between the UPS and the management system used.

Modbus / Jbus protocol converter via RS485 output for UPS monitoring in BMS (Build Management System).

Profibus DP
External accessory that allows the UPS to be integrated into a Profibus DP network. With this device UPS management and monitoring can be integrated into a control system based on one of the most widely used bus buses in the industrial field for communication between control / automation systems and distributed I/O.

Remote Panel
Remote Panel that allows remote UPS monitoring and real-time detailed overview of operating conditions; it can display on the display the values of the UPS specifying input and output, and battery measurements. The graphic display has a high definition and manages 7 languages: English, Italian, German, French, Spanish, Russian and Chinese.

External battery temperature sensor
The UPS has a dedicated input to detect the temperature inside a Remote Battery Box and display the temperature on the UPS display.

External maintenance bypass
You can install a remote maintenance bypass on a peripheral electrical board, for example to allow UPS to be replaced without interrupting power supply.

The SPH IND UPS may be paralleled for power capacity or for redundancy up to 8 units to increase the power capacity or configuring a parallel redundant UPS system. The standard version is not provided with this feature which is optional and field upgradable.

In/outlet terminals are placed in the front bottom under the switch isolators of the apparatus. On request is possible to provide the apparatus with input/output and battery terminals from the top.
