The G4K BLACKBOX Unit
The innovative design of the G4K BLACKBOX has been uniquely adapted to address
the individual n eeds & requirements f or almost a ny business and/or application.
The m odular & expandable design p rovides m aximum f lexibility f or cu stomized
requirements.
The m ain b ase (front end) of the unit is comprised o f three m odules na mely the
Central Processing Unit (CPU), the Digital Signal Processing (DSP), & t he Power
Supply (PS).
The functions for the CPU are mainly data compression, file handling & facilitation
of co mmunication i nterfaces. T he C PU f eatures an A C/DC p ower s upply, D C/DC
converter, an automatic s election o f h ighest v oltage & an u ltra cap acitors' ride-
through for up to 25 seconds.
The DSP is responsible for capturing the electric signal & converting the waveforms
to digital data. The DSP's capabilities include simultaneous 12 channel sampling at
250 kHz (4 µsec), full scale measurements 10 x from nominal voltages & currents at
an extremely high accuracy. The CT's dual range with auto selection ranges from 0
- 5A, 0 - 50A R MS & has a r eading a ccuracy o f 0 .1%. There ar e a t otal of six (6)
apertures. Typically only the first four (4) are used as current inputs for I1, I2, I3,
and IN (Neutral current optional as the fourth input).
The PS facilitates a wide r ange of in puts t hat comply with the highest standards
set by the industry. The power supply module contains internal backup circuitry to
hold in ternal v oltage during m omentary t ransients an d d isturbances. T hus, w hen
powering off the unit, it continues operating for up to 1 minute. The power supply
supports the following power sources:
DC 100-300V
AC 100-260V, 60/50 Hz (recommended)
PoE 48V
The top of this f ront end b ase f acilitates t he connection for t he PT100
thermostat & th e D C Converter i nput. In a ddition to th e P T100 c onnection, the
G4K is equipped w ith 2 a dditional internal t emperature s ensors ( PS a nd D SP
modules). T he o perating t emperature r anges fr om -20 to + 70°C & the s torage
temperature ranges from -30 to +80°C. The DC Converter ranges from an input DC
of 48 VDC & a minimum voltage for PoE of 48 VDC.
