Medical Isolated Power Supply System

DELIVERING SAFE AND SECURE ELECTRICAL POWER
IN CRITICAL AREAS OF HEALTHCARE FACILITIES

Medical Isolated Power Supply System

NO MORE UNWANTED TRIPPINGS!

When it is necessary to guarantee safety and service Incoming Supply
continuity and to avoid interruptions of power supplies
in hospitals and other medical locations, it is Medical Isolation
mandatory to install Medical Isolated Power Supplies Transformer
(IPS) or Medical IT Systems to detect and signal the first
earth fault. IPS-DB complete with IMD,
Double Pole Circuit Breaker.
POLYLUX Medical Isolated Power Supply employs the
state-of-the-art technology in Remote Signalling To Double Pole
measurement, detection and signalling. It is designed Panel Socket Outlet
according to IEC 60364-7-710 for Group 2 medical
locations. POLYLUX Medical IPS System main
components consist of:

• Insulation, load and temperature monitor.
• Single phase isolation transformer.
• IPS distribution board with double

pole miniature circuit breakers.
• Remote signalling panel.

INSULATION, LOAD AND TEMERATURE MONITOR

The insulation, load and temperature monitor or insulation monitoring device (IMD) ensures absolute
reliability of measurement by means of a codified signal that is able to detect the disturbances generated
by the common devices in the operating theatres/rooms and critical care areas; this avoids unwanted alarm
signalling.

The VA40 model measures insulation resistance, insulation impedance, load and temperature of the
medical isolation transformer.

ISOLATION TRANSFORMER

The Isolation Transformer is specially designed for medical locations where there is a galvanic
separation between the primary and secondary windings. The primary side is connected to the
TN system and the secondary is converted to an IT system. An electrostatic screen or shield is
installed between the windings to reduce electrical interference, and has an insulated connector
for connection to the equipotential bonding.

Technical Features: : THX series
: 1, 2, 3.15, 4, 5, 6.3, 8, 10 kVA
Model : AC 230.240 V. 1 Phase, 50…60 Hz

IPS DISTRIBUTION BOARD

The IPS distribution board houses the insulation, load and temperature monitor, double pole
miniature circuit breakers and other accessories. It can be constructed for wall mounting or floor
standing. A transparent acrylic window allows viewing of the insulation, load and temperature
monitor’s parameters without the need of opening the door.

Technical Features: : DB-IPS-W series
: wall ( floor mounting on request)
Model : sheet steel
Mounting type : min. 1.2 mm (sides and door)
Material : epoxy powder coating RAL 9002 (white)
Thickness : transparent acrylic
Finishing : top and bottom
Front door window : IP 31
Cable entry : miniature double pole, type C, 6 kA
Protection degree : max.9 ways-475 mm x 110 mm x 380 mm
Circuit breaker
Dimensions (W x D X H) max.18 ways-475 mm x 110 mm x 530 mm
: 10-20 kg
Weight : MS IEC 60439. MS IEC 60898
Standards/Certifications
(other specifications on request)

REMOTE SIGNALLING PANEL

The standard IEC 60364-7-710 requires an acoustic and visual alarm system to be installed at a
suitable place so that the medical staff can permanently monitor it. In most cases, the remote
signalling panel is installed on the operating theatre/room panel or at the nurse station.
