NV175 HIALT Handbook
3. Options –M and –MR meet IEC60601-1 Edition 2 Reinforced spacings with the following limitations:
Channel 1 cannot be 5V model (T1 and T2 with foils)
Channel 2 cannot be fitted
Cannot be global option variants
4. There is no –F, -M, -MR or –I options for the NV175 –H or –HR high altitude models
5. Fan versions:
Channel 1 with G output, 25V maximum with 5V channel 2 maximum output current of 7A.
Channel 1 with G output, 25V maximum with 7V channel 2 maximum output current of 5.5A.
Channel 1 with G output, 5L channel 2 maximum output current 1.8A.
Channel 2 with T and F outputs, channel 2 maximum output current of 9A.
Channel 4 maximum output current of 1.5A
6. Model NV1-1G000 (with or without global option or –M/-MR option) may also be run with Channel 1 output
voltage range 22.5V to 28V with maximum current of 7.5A and maximum power of 180W
7. Model NV1-1G000 (with or without –M option) may also be run at 88.9Vac to 240Vac nominal input (tested for
continuous running at 80Vac input), output: 24V to 28V at 6.25A maximum current and 150W maximum power

Capacitive Loads
Outputs on NV175 are designed for use with capacitive loads up to the value shown in the table below.
Applications where a discharged capacitor is switched onto the power supply output create additional loading for
which a non standard product may be required.
Consult factory for details.
