As shown in Fig. 2-1, output voltage never decreases below 90% of full output rating
during the source transfer. Output voltage recovers to full rated output within 2 cycles
following transfer. Under the test conditions in which the waveform was recorded,
output voltage was measured to be 86.30 volts RMS with 80% of full rated load applied.
Video-only services using equipment powered by standby power supplies should
exhibit little if any disturbance within the customers’ homes during a source transfer.
On the other hand, critical services such as VoIP, telephony grade communications
and data transfer may experience undesired disturbances from source transfers
between commercial AC line and inverter power. Such services may be highly
intolerant of any power anomolies, even minor disturbances that would never be
noticed on video-only services. For mission-critical services requiring an exceptionally
high degree of power integrity, system operators are advised to consider using one of
the MP Plus Series true-UPS power supplies offered by Multilink Broadband. Contact
you local Multilink sales representative for further information.
The power supplies documented in this instruction manual have been designed to
support optional HMS status monitoring. The HMS protocol supports communication
between the power supply and the monitoring device via an RS-485 serial port in an
external modem. HMS status monitoring may be installed either at the factory or in the
field as an added option.
