Led Power
3.10.1.1. Power supply
Powering of the release by the MEASURING Module takes place via busbar voltage.
The powering stage is capable of operating starting from a voltage of 80 Vrms two-phase phase to phase up to 897 Vrms ( 1.3 *
690 Vrms ) three-phase phase to phase at its input (coming directly from the busbars or from a transformer secondary).
The minimum supply specifications are described in sect. 3.3.8.
3.10.1.2. PR330/V parameters
All the parameters of the PR330/V can be adjusted in the Settings-Modules menu

Mod.
Module PR330/V allows the primary voltages to be read and processed by implementing a
series of protection and measuring functions.
The module also provides energy for powering the protection release even in the absence of
Vaux, nil current or CB open conditions.
PR330/V can function with direct connection to the bars of the CB for phase voltage
values of up to 690V. It is obligatory to use an insulation voltage transformer for connection
to the busbars in systems with over 690V rated voltage (up to 1150V) or with a PR330/V
module connected by external sockets.
The module comes with a "Power" LED, which indicates whether the energy from primary
voltages is sufficient to supply the protection release, and a sealable disconnector for di-
electric strength tests.
The menu in the protection release allows various different parameters to be adjusted:
- Selezione tensione nominale
- Rated voltage selection
- TV presence signalling
- Selection of the primary and secondary voltages of the TV
- Power flow setting
- Neutral enabling (only available with three-pole CB)
A further two parameters are available in the menu when the module is installed in PR333/P:
- Phase sequence: sequence control enabling and thresholds
- Cos ϕ measured: control enabing and threshold of the Cos ϕ measured module.

Notes
In the absence of the TV, the primary voltage meas-
urement on the display is the one read on the bars.
If the TV is present, the measurement on the display
considers the transformation ratio of the TV estab-
lished by the primary and secondary voltage settings.
