Dimensions LAH 25-NP (in mm. 1 mm = 0.0394 inch)
Remarks
• I
S
is positive when I
P
flows from terminals 1, 2, 3 (IN) to
terminals 6, 5, 4 (OUT).
• The jumper temperature and PCB should not exceed 100°C.
• This is a standard model. For different versions (supply
voltages, turns ratios, unidirectional measurements...),
please contact us.
