ITZ 2000-SBPR FLEX ULTRASTAB
Secondary current monitoring
The rack electronics incorporates a 0.1 Ω resistance in series with the measuring resistance for the monitoring of the secondary
current.
A BNC connector located on the rear panel provides a low-precision voltage output ±1 V full-scale which indicates a secondary
current flowing through the measuring resistance and the 0.1 Ω resistance.
The voltage on this connector is equal to.
As one example, if

, the voltage on this connector is −1 V.
As another example, if

Delivery package
The LEM ITZ 2000-SBPR FLEX UL TRASTAB package contains by default:
●
19-inch rack-mount ITZ FLEX ULTRASTAB electronics
●
Transducer head
●
European (Schuko CEE 7/7) and US/Japanese mains cables, 2 m each (with three-pole IEC C13 female connector).
●
Short-plug for 4 mm banana terminals and 15-pin D-Sub short-plug for analog output connector
(back panel of electronics rack)
Mandatory accessories
The 3 following accessories have to be separately ordered as per the table hereafter, otherwise the ITZ FLEX ULTRASTAB can
not operate without them:
●
Transducer head cable (interconnecting cable between transducer head and electronics rack)
●
Analog output cable
●
Programming plug 25-pin D-Sub (for connector on the head)
