FPS1000 Instruction Manual

CHAPTER 4 FUNCTIONS AND FEATURES

4.1 Input Voltage Range

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.

4.2 Output voltage trimming

The output voltage can be adjusted within the specifications via the V_Trim pin at the In/Out connector. Refer to Fig 4-1 typical connection and calculation of the adjustment resistors:

Note that the Over Voltage Protection may trigger if the output voltage exceeds the maximum voltage specification.

4.3 Over Voltage Protection (OVP)

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.

4.4 Over Current Protection (OCP)

A constant current limiting with automatic recovery is provided. The OCP operates when the output current exceeds 105%~125% of the rated output current. The output voltage recovers automatically when the overload condition is removed. Avoid operating the power supply under overload condition for long time as it might cause damage to the power supply.

4.5 Over Temperature Protection (OTP)

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.

4.6 Auxiliary 12V output

An isolated 11.2V~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 FPS1000 units. Use this output for the control and monitoring signals described in this chapter or to operate application circuits.

4.7 Over Temperature Alarm

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. Refer to Fig 4-2 for typical application.
