KEISOKU GIKEN LOAD EDGE Series - Current Monitor

Load Edge Series
Connections 25
2.4 CURRENT MONITOR
This CURRENT MONITOR can be used when you observe a current waveform by an
oscilloscope.
ELZ-175 has four ranges of current monitor for accuracy.
･50 ５０Ａ／５Ｖ
･25 ２５Ａ／5Ｖ
･10 １０Ａ／5Ｖ
･80 ８０Ａ／5Ｖ
CURRENT MONITER RANGE
・ The CURRENT MONITOR output is not isolated. Pay great attention on its
connection. Improper connections would cause damage.
・ Monitor output voltage range is between 0V and 5V depending on current
measurement value between 0 A and setting range (10A/25A/50A/80A), Output
impedance : 50Ω (typ.)
・ In case of loading more current over setting current range, maximum output
voltage (8V) is generated (For example, When ELZ-175 sets 16A at 10A range,
CURRENT MONITOR generates 8V. but when ELZ-175 sets 18A at 10A range,
CURRENT MONITOR generates 8V in like wise.)
・ An equivalent circuit in terms of the current monitor of this product is shown.
