Notes:
1.
The MC1000A is supplied with a US style power cord. Units purchased in other countries must supply their own certified rated power cord.
2.
The reference output and external input is short circuit protected by limiting the current to 25mA. Over and Under voltage protection is
available, but continued use will degrade or damage the unit.
3.
The Min Load Impedance represents the smallest allowable terminating resistance. Applying lower impedances will cause the short circuit
protection to limit the output voltage. Continued use in this mode will cause circuit degradation and eventual circuit failure.
4.
The MC1F10 blade is supplied with the unit. All other blades specified may be purchased separately through Thorlabs, Inc.
5.
Do not use a null modem cable.
