UPS+

To maximise the seismic monitoring system’s operational uptime, an Uninterruptable Power Supply (UPS+) is recommended at each seismic station. Due to the sensitivity of microseismic measurements to electrical noise and the effect which a ‘dirty’ power supply can have on the digitization of minuscule analogue signals, it is highly recommended that a good quality power supply is used to power the acquisition hardware. All IMS monitoring hardware is tested with IMS UPS’s for electrical noise and interference.

Besides the usual benefits of using a UPS+ (i.e. battery backup and surge protection), the IMS UPS+ has the added advantage of providing a bi-directional communications interface to compatible connected equipment. This interface provides the ability to remotely monitor and report the presence of mains power, perform hard resets (power cycles) and inform attached equipment of imminent load shedding (due to battery depletion in the event of extended power failures), allowing the seismic station sufficient time to gracefully shutdown and backup any unsent data. The multiple, individually monitored and controlled,  DC output ports of an IMS UPS+ can also be remotely monitored and controlled via Synapse which reports such parameters as output voltage and current, battery voltage and level of charge.

Key Features

  • wide range universal input voltage: 90 – 260 V AC, 50 – 60Hz
  • built-in surge / overload protection
  • individually, remotely switchable output ports
  • battery state-of-health and internal resistance measurement
  • output voltage on AC power: 15.5 V DC
  • output voltage on battery power: 10.5 – 13.8 V DC
  • supports 1 to 4 independent channelswith remote load sensing
  • dedicated 48 V DC output port for DSL Modems, and other 3rd party telecommunications equipment
  • battery life: 8 hours for a single unit (assuming typical load with 7 Ahr battery)
  • communication interface with netSP for UPS+ status reporting
  • status LEDs indicate power and battery condition of the UPS+

Variants

IMS can provide UPS devices with a number of configurations, including:

Active Temperature Controller UPS:

An IMS UPS with temperature sensor probes, heater and cooling fan outputs. This UPS can be used to extend the operating temperature range of an IMS station and protect other IMS devices, to allow an IMS station to run in the most extreme conditions.

DC-input PDU:

An IMS PDU (Power Distribution Unit) shares most features with an IMS UPS, but is powered by an externally provided DC input (10-18 V DC) rather than AC, and does not make use of an external battery. This device can be used in low-voltage (9-18 V DC) applications where an AC source is not available; examples include solar-powered stations or remotely installed 3rd party UPSs.
