Please select Yes if you need medical approval (IEC/EN/UL 60601).

If you do not know or do not mind, please leave set to I don't mind.

Please select the minimum required isolation.

If you do not know or do not mind, please leave set to I don't mind.

Please select the maximum allowable Earth leakage for this power supply.
Please select Class 2 if you need a power supply which does not need an Earth connection.
All leakage current values are stated at 264VAC and 63Hz to simplify comparison.

Note: 300µA at 264VAC / 63Hz is approximately equivalent to 110µA at 110VAC / 60Hz.

Please select the case option you need.

Enclosed for power supplies which have both a cover and chassis.
Chassis only for power supplies which are supplied with no cover.
Open frame for power supplies which are supplied with no additional protective metalwork.
DIN rail for power supplies which are designed to be mounted directly to a DIN rail.
Adapter for plastic cased, desktop power supplies.
PCB Mount for power supplies which are designed to be mounted directly onto your equipment's PCB.

Note: The unit covers and chassis (except for adapters) are designed to protect only skilled personnel from hazards and must not be made user accessible.

Please select the type of cooling required.

Fixed or variable speed forward air fan for power supplies fitted with a fan blowing from input to output.
Variable speed forward air fan for power supplies fitted with a temperature-controlled fan blowing from input to output.
Fixed speed forward air fan for power supplies fitted with a fixed-speed fan blowing from input to output.
Standard reverse air fan for power supplies fitted with a fan blowing from output to input.
No fan (customer cooling) for power supplies which are not fitted with any fan (some units may rely on air movement from additional fans).
Convection cooled for power supplies cooled only by convection (no additional fans needed).
Baseplate cooled for power supplies cooled by mounting onto a 'cold wall'.

Please select the type of connection for the AC input.

Screw for screw terminal or barrier strip connection.
IEC for IEC input connection.
Molex / JST for Molex or JST input connection.
Faston for faston input connection.
PCB mount for power supplies which are pinned to be mounted on PCB by the customer.
Flying leads for permanently wired, unterminated input cable.
Positronic for Positronic branded input connector(s).

Positronic connectors are used on FPS1000 power supplies -

Please select the number of input fuses needed.

Single fuse for only one supply line fuses.
All supply lines fused to have a fuse in each of the supply lines.

If you do not know or do not mind, please leave set to I don't mind.

Please select the type of AC input supply being used.

Single phase for one phase input (normally domestic supplies are single phase).
Three phase for three phase input (usually 340 - 575VAC). This is mainly for high power equipment.

If you do not know or do not mind, please leave set to I don't mind.

Please select Yes if you need a power supply with an indicator (accessible logic pin or LED indicator) for when the AC supply is OK.

If you do not know or do not mind, please leave set to I don't mind.

Please select Yes if you need a power supply with an indicator for when the DC output (all DC outputs for multiple output power supplies) are operating within regulation.

If you do not know or do not mind, please leave set to I don't mind.

Please select the type of global control required. This control will inhibit or enable all outputs of the power supply (usually not affecting the auxiliary / standby outputs).

Inhibit - with no input, the power supply will operate.
Enable - with no input, the power supply will not operate.
ATX Enable - with no input, the power supply will not operate. This operates the same way as the enable on ATX power supplies for PCs.
I²C/PMBus Digital Control - for a communication bus or digital control is required.
