Data Sheet

High Voltage Power Feed Equipment (PFE)

Spellman's shipborne and land-based power feed equipment (PFE) is used to power submarine fiberoptic cable repeaters for telecommunications shore stations and during cable laying and repair operations. We are the leading supplier of Power Feed Equipment to the Submarine Telecom Industry.

Spellman's Portable PFE (PFE-P) provides the consistent, reliable and safe high voltage power in a compact footprint. The PFE-P incorporates the same advanced digital management system as Spellman's Shipborne PFE (PFE-SB); including voltage and current control, push-button polarity setting, continuous monitoring and alarm reporting from the Main Control Unit (MCU).

The system can be configured with the optional System Management Terminal (SMT) to provide programmable electroding functions, data and event logging and fully adjustable ramp rates, trips and alarms.

The system is powered from a 230Vac single phase mains supply.

SPECIFICATIONS

Input Voltage:

230Vac ±10% 50/60Hz (Single Phase)

Input Current:

50A ac maximum at minimum line voltage

Output Voltage:

0 to 6kV, linearly controllable via the MCU

Output Current:

1A maximum at any output voltage up to 6kV

Polarity:

Reversible by selecting positive or negative mode on the MCU when the HV is disabled.

Voltage and Current Ramp Rates:

See MCU and SMT description.

Voltage Ripple:

<0.1% pk-pk of max output +1Vrms

Stability:

Typically <0.25% over any 24 hour period with a temperature range of 0°C to 30°C.

Voltage Regulation:

Load: 0.05% of full voltage +500mV for full load change

Line: +/-0.05% of full voltage +500mV over specified range

Current Regulation:

Load: 0.05% of full current for any voltage change

Line: +/-0.05% of full current over specified input range

Temperature Coefficient:

< 100 ppm/°C

Operating Temperature:

0 to +30°C

Humidity:

0% to 90%, non-condensing

Cooling:

Local cooling and/or ventilation needs to be adequate to balance the system heat dissipation of 1.2kW at 6kV, 1A output.

Safety:

The MCU is equipped with an Emergency Stop Button. Terminals in the rear of the cabinet allow connection of external emergency stop devices.

Clamp/Safety Chassis:

Protects the connected line and PFE-P. A HV dump circuit will quickly and safely discharge the system in the event of emergency shutdown Front panel mounted lamps indicate if the PFE-P output is safe or energized.

HV Output:

The unit is supplied with 10 meters of RG213/URM67 cable terminated with a 15kV Lemo plug. See HV Output cable detail dwg.

Control:

Manual controls for output voltage and current are provided on the MCU front panel. The PFE-P is capable of operating in either Constant Current or Constant Voltage mode as required by the operator.

Protection:

Over-voltage and Over-current protection levels are settable on the MCU. In the event of a cooling fan failure, the internal temperature limit ensures a safe system shutdown.

Regulatory Approvals:

RoHS compliant. Designed to meet IEC/UL 61010-1 safety requirements for electrical equipment for measurement, control and laboratory use; CAN/CSA-C22.2 No.61010-1.

Specifications

Main Control Unit (MCU):
The system can be controlled manually using the MCU front panel controls.

Main Control Unit
