Supported Firmware Modules
Power Quality (PQ) — extends the measured quantities for inter-harmonics, flicker and selective voltmeter,
archive options for PQ main and PQ events archive, so as that the instrument can serve as a fully compatible
PQI-S - class S power quality analyzer.
General Oscillogram (GO) — Adds a feature that allows recording of raw signal samples.
Ripple Control Signal (RCS) — Allows archiving of ripple control signals (RCS, HDO) data-grams and
theirs voltage levels.

Types and accessories
The SMY 133 is available in several configurations according to the customer requirements
. See the ordering
scheme on figure 1.
Digital I/O
Communication Interface
N = USB, no remote comm. link
4 = USB, RS-485
E = USB, Ethernet 1OBaseT
Current Inputs
X/5A = 5A AC (standard indirect measurement)
X/1A = 1A AC (standard indirect measurement)
X/1OOmA = 1OOmA AC (indirect measurement)
X/333mV = input for sensors with 333mV output

Instrument Model
Auxiliary Power Supply
SMY 133 = Power analyser, datalogger, 3U, 3I
U = 85 V ÷ 275 VAC, 8O V ÷ 35O VDC
S = 1O V ÷ 26 VAC, 1O V ÷ 36 VDC
L = 2O V ÷ 5O VAC, 2O V ÷ 75 VDC
Nominal Measuring Voltage
23O = 23OV/4OOV
1OO = 57,7V/1OOV
4OO = 4OOV/69OV
N = without I/O
RR = 2× relay 1× logical input 24V
RI = 1× relay 1× pulse 1× logical input 24V
II = 2× pulse 1× logical input 24V
