P850 Series

Rectifier and charging

The P850 UPS equipped with SCR based rectifier offers a very high reliability compared to switchmode type, simple design and gate firing, high power availability through a single unit, very robust and fault tolerant. Lower voltage dc bus such as 125Vdc or 250Vdc are preferable to keep your lower battery number of cells and help reducing battery reliability and maintenance requirements.

Industrial vs IT grade UPS

Industrial applications such as Oil & Gas, Power Generaton and process require conservative design, models are available for longer period of time backward compatibility, front access, IEEE446. Larger rectifier/charger can also be needed to accommodate faster recharging of batteries or for large capacity batteries. Water and compressed air cooling is available for harsh environments. 12 pulse input rectifiers with or without shielding is available for large power applications or for low input THDi needs.

Short Design Guide

  1. Battery type and needs: Ex. Ni-Cd batteries do not fail open circuit, additional filtering for VRLA which tolerates limited discharge cycles, lower number of cells for reduced issues and maintenance.
  2. Environment: seismic, dust, salt and corrosive fumes, heat or cold ambient, zero-energy safety, ac and dc ground leakage alarm needs.
  3. Non linear load requirements: harmonics, inrush current, crest factor.
  4. Design life and spare: 20+ year and spares available for 12+ years.
  5. Communication and alarms: Modbus, web page, IEC 61850, 4-20mA transducers, alarm relays.
  6. Grid conditions at the point of application: poor and fluctuating conditions, high harmonics contents, high frequency noise, phase balancing issues.
  7. Consider high frequency rectifiers instead of SCR type. This provides a very high availability through multiple parallel unit, near unity power factor correction, very low THDi, more compact size, redundancy, easier service and replacement, future growth expendability.

Emergency Power Off (EPO)

EPO is a remote disconnect EPO switch is used to shutdown the inverter/UPS and to disconnect energy sources during an emergency. For ex. UL1778, NFPA70, IEC364-4, EN50091 standards govern the requirements of an EPO. UL and NFPA require using an EPO in information rooms (ex. data centers). No EPO is required by these standards for industrial applications such as feeding motors or chemical process, control rooms. An EPO is composed of 2 devices: the control and the disconnect itself. The control can be located inside the system but preferably remotely at the room entrance for example, that operators won’t be exposed to fire or electrical danger in case of an emergency. It can consist of a push button which command the opening of the disconnect. The disconnect device such as a circuit breaker or a contactor will be tripped open in an emergency. All energy sources need to be isolated including the backup battery within few minutes following an emergency event.

Mistakenly or accidentally operation of EPO can lead to major unexpected shutdowns or safety issues and unpleasant consequences such as loss of productivity and expensive process restart. Considerations of using and locating an EPO must be seriously analyzed in order to keep the application safe and reliable.
