Refer to figures 1-7 for supply-load connection information.
** Output current and power, as measured at output terminals, must be less than or equal to
quoted maximum values for a given ambient temperature.
*** Regulatory agency compliance applies only for operating frequencies between 47-63Hz.
No safety agency approvals for 100-380 VDC operation. Minimum turn-ON voltage for
DC Input is 110 VDC, unit will operate as low as 65 VDC after Power-up. Lambda doesn’t
recommend operation below 100 VDC for more than one minute, or damage may occur.
