FlatPAC-EN Design Guide

FlatPAC-EN™

EN Compliant Autoranging Switcher

Overview

The FlatPAC-EN is an ultra low profile switching power supply that provides up to 500 Watts from up to 4 isolated outputs. It operates on either 115 or 230 Vac nominal (47-63 Hz), or 250-380 Vdc. The two-output version contains 1 full brick and 1 half brick. The three-output version contains 3 half bricks. And the four-output version contains 1 half brick and 3 quarter bricks.

The use of these converters gives the FlatPAC-EN the inherent power flexibility typical of all Vicor products. With dimensions of 1.4" H (35,6mm) x 5.0" W (127mm) x 9.2" L (233,7mm), the FlatPAC-EN provides a power

density greater than 7W/in3. It is factory configured to meet user output requirements. Note: The FlatPAC-EN does not have an internal fan.

Mechanical Considerations

The FlatPAC-EN is mounted on the bottom surface using standard 8-32 or 4 mm screws (cannot be mounted from the front.)

Maximum allowable torque is 5 in. lbs.,. The maximum penetration for mounting holes A1, A2, A3 and A4 is 0.125 in. (3mm) and for mounting holes B1, B2, C1 and C2 is 0.250 in. (6mm). The minimum recommended mounting holes are as follows:

1.For standard mounting (forced air cooling), use A1, A2, A3, A4 mounting holes.

2.For standard mounting (conduction cooling), use A1, A2, A3, A4, B1 and B2 mounting holes.

3.For a Vicor 2 Up FlatPAC retrofit replacement, use C1 and C2 as these two are identical to the recommended mounting holes on the FlatPAC.

For increased ruggedness, additional mounting holes can be used to secure the power supply.

The FlatPAC-EN does not have an internal fan. It can be conduction or convection cooled (same model).

Avoid excessive bending of output power cables after they are connected to the output terminals. For high-current outputs, use cable ties to support heavy cables and minimize mechanical stress on connectors. Be careful not to short-out to neighboring outputs. The maximum torque recommended on output nuts is 10 in. lbs.

For applications that require vibration levels above MIL-STD-810E, a shock absorbing mount design is required.

FlatPAC-EN Do’s and Don’ts

Do not exceed an operating case temperature of 90oC. To prevent an overtemperature condition, an external fan may be required.

Run the output (+/–) power cables next to each other to minimize inductance.

Do not attempt to repair or modify the power supply in any manner as this action will void the warranty. In the event of problems, contact Westcor’s Customer Service Department at 1-800-797-5678 or (408) 522-5280.

Insert proper fault protection at power supply input terminals (i.e., a fuse).

Use proper size wires to avoid overheating and excessive voltage drop.

FlatPAC-EN Design Guide

Technical Description

The FlatPAC-EN consists of an off-line single phase autoranging front end, EMI filter, customer interface, power supply control circuit, associated housekeeping circuits, a MiniHAM module and a selection of Vicor’s 1st Generation (VI-200 and VI-J00) and/or 2nd Generation (Maxi, Mini and Micro) DC-DC converters.

The MiniHAM was specifically designed for EN compliance using passive filtering. Unlike active PFC solutions, the MiniHAM generates no EMI, greatly simplifying and reducing system noise filtering requirements. It is also considerably smaller and more efficient than active alternatives and improves the unit’s MTBF. It will provide harmonic current compliance at 230Vac input up to 425W of output power. Input AC mains voltage is applied to input connector MBJ1 (see page 6) and the input current is passed through an EMI filter designed to meet conducted noise limit of EN 55022, Classes A and B specifications. Certain configurations may require Westcor’s optional external in-line filter to meet EN 55022 Class B.

At start-up, the microcontroller verifies that the input voltage is within the specified operating range. Once this occurs, the microcontroller closes the safety relay and puts the autoranging front-end in the correct mode (closing or opening the Doubler relay). The autoranging front-end has two modes, the doubler mode (90Vac - 132Vac) or bridge rectifier mode (180Vac-264Vac, 250Vdc-380Vdc). Inrush current is limited by a PTC thermistor. The PTC is shunted out (by closing the Inrush relay) when the output voltage has charged up the bus capacitors within the specified range (205Vdc-390Vdc). Approximately 1 second after the application of the input voltage, the bus voltage is within operating limits and the AC OK signal asserts to a TTL "1", indicating the input power is OK. After AC OK is asserted high, the user can now control the power outputs.

Output voltage conversion is achieved by Vicor’s 300Vin family of Zero-Current-Switching (ZCS) DC-DC converters. These are forward converters in which the main switching element switches at zero current. This patented topology has a number of unique attributes: low switching losses; high frequency operation, resulting in reduced size for magnetics and capacitors; excellent line and load regulation; wide adjustment range for output; low EMI/RFI emission and high efficiencies.

At initial power-up, all outputs are disabled to limit the inrush current and to allow the DC bus potential to settle to the correct operating level. A low-power transformer flyback circuit converts the high voltage DC bus into regulated low voltage to power the internal housekeeping circuits as well as the auxiliary +5Vs located in the interface connector.

An output Enable/Disable function is provided to control Vicor’s DC-DC converters. If the Enable/Disable control pin is pulled low, the modules output is disabled. The nominal delay associated for an output to come up when measured from release of the Enable/Disable pin is 9-12 ms. The General Shutdown function controls all outputs simultaneously and works in a similar manner.
