ITZ 2000-SPR 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 (

(A) × 0.1 Ω × 10) /

(Volt).

As one example, if

is 2000 A and

is 2000, the voltage on this connector is 1 V.

Similarly, if

is −2000 A and

is 2000, the voltage on this connector is −1 V.

As another example, if

is 62.5 A and

is 125, the voltage on this connector is 0.5 V.

Similarly, if

is −62.5 A and

is 125, the voltage on this connector is −0.5 V.

Delivery package

The LEM ITZ 2000-SPR 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)
