The FPS1000 series power supply is an established, field-proven, “High Power Density” design, aimed at key projects, where performance and reliability is paramount.
One 19in x 1U rack can hold up to three 1000W rectifier modules, with up to eight modules in parallel to provide up to 8kw of power with N+1 Redundancy. There are a number of programming and status signals, allowing end users to configure a system that suits their application.
Input voltage is single phase 85-265Vac (47-63Hz). The power supply can be operated also with a DC input voltage, 120-330VDC but the safety approvals apply to the AC voltage only. Input voltage which is out of the specifications might cause damage to the unit.
The OVP triggers when the output voltage exceeds the maximum rating and reaches the OVP limit. When the OVP is triggered, the output voltage shuts down.In order to resume operation, the AC input voltage should be removed for more than 30 sec. The OVP level is factory set and is not adjustable.
The OTP is activated when the ambient temperature or the power supply internal temperature exceeds a safe temperature. When the OTP is activated, the power supply output shuts down. The output recovers automatically when the ambient temperature or the internal temperature cools to a safe limit.
An isolated 112.2V – 12.5V output is provided ( Referenced to the signals_return potential). The maximum output current from this output is 0.25A. This output has a built-in Oring diode to allow paralleling FPS100 units. Use this output for the control and monitoring signals described in this chapter or to operate application circuits.
An open collector output provides an Over Temperature Alarm approx. 10°C below shut down by the OTP. The open collector output is referenced to the Signals_Return potential and is isolated from the power supply +V and -V terminals.The maximum sink current is 10mA and the maximum external voltage is 15V. See Manual for further information.
An open collector output provides a low output voltage detection signal. The open collector output is on when the output voltage is higher than 80%+/-5% of the rated output voltage of the power supply. The open collector output is referenced to the Signals_Return potential and is isolated from the power supply +V and -V terminals. The maximum sink current is 10mA and the maximum external voltage is 15V.
A Remote On/Off control input is provided. The Remote On/Off input is isolated from the power supply +V and -V terminals and is referenced to the Signals_Return potential. The Remote On/Off can be operated either by electrical signal or by dry contact.
(1) Operation by electrical signal:
The maximum sink current is 2.6mA and the maximum external voltage is 15V.
(2) Operation by dry contact (relay or switch):
When the Remote On/Off function is not used, connect a short circuit between the On/Off control and the Signals_Return.
