Option(1)

Description

HFB

High Frequency Burst: Improved burst capability of driver by means of external buffer capacitors. Recommended if more than 10 pulses with less than 10 μs spacing are generated.

HFS

High Frequency Switching: External supply of auxiliary driver voltage (50-350 VDC according to type). Necessary if the specified “Maximum Operating Frequency” shall be exceeded.(2)

LP

Low Pass: Low pass filter at the control input. Propagation delay time will be increased by ~50 ns. Jitter + 500 ps.  Improved noise immunity and  less critical wiring in high speed applications. (3)

ST

Stage Tapping:  Connectors at the individual stages of stack in order to utilize single power semiconductors. To achieve fast rise times also at very low operating voltages (<0.01xVo).

DT

Delayed Trigger: “Total Turn-On Time” irreversibly increased to >1 μs. Required if national or international export restrictions apply (“dual use  products”). (2)

ISO-25

25 kV Isolation:  Isolation Voltage increased to  25 kVDC. Housing dimensions may change for some models.

ISO-40

40 kV Isolation:  Isolation Voltage increased to  40 kVDC. Housing dimensions may change for some models.  Only in connection with option PT-HV.

ISO-80

80 kV Isolation:  Isolation Voltage increased to  80 kVDC. Housing dimensions may change for some models.  Only in connection with option PT-HV.

ISO-120

120 kV Isolation: Isolation Voltage increased to 120 kVDC. Housing dimensions may change for some models. Only in connection with option PT-HV.

I-PC

Integrated Part Components: Integration of small part components according to customer’s specifications (e.g. buffer capacitors, snubbers, damping resistors, diodes, opto couplers).(2)

I-FWD

Integrated Free-Wheeling Diode:  Built-in parallel diode with short recovery time. In connection with inductive load only.

SPT-C

Shielded Pigtail for Control Connection: Cable (l=300mm, Z=100Ω) with LEMO plug+socket and 100Ω termination. Improved noise immunity in case of long distance to driver circuits.(3)(4)

PT-C

Pigtail for Control Connection: Flexible leads (l=75 mm) with PCB connector. This option is only relevant for switching modules with pins. Recommended for modules with options CF & GCF.

PIN-C

Pins for Control Connection: Gold plated pins for printed circuit board designs (special sockets available). This option is only relevant for switching modules which have pigtails as standard.

PT-HV

Pigtails for HV Connection: Flexible leads with cable lugs. For increased creepage. PT-HV is standard for all types with >25 kV switching voltage. Not recommended in extremely fast circuits.

ST-HV

Screw Terminals for HV Connection: Threaded inserts at the bottom of module (if not standard). For PCB design. Operation above 25 kV requires liquid insulation (Galden®/Oil) or potting.

UL94

Flame Retardant Casting Resin: Casting resin according to UL-94-VO. Minimum order quantity required. (2)

TH

Tubular Housing: Tubular instead of rectangular housing. Adaption to specific ambient conditions or in case  of difficult assembly situations. (2)

FC

Flat Case: Height of standard plastic housings reduced to 19 / 25 mm. Not in combination with cooling options CF, GCF and DLC.

ITC

Increased Thermal Conductivity: Special moulding process to increase the thermal conductivity of the module. Pd(max) will be increased by approx. 20-30%. (2)

CF

Non-Isolated Cooling Fins: Standard sizes in categories I to VII according to model. Nickel plated copper 0.5 mm, fin height 35 mm. For air and liquid cooling (e.g. Galden® or oil).

CF-1

Non-Isolated Cooling Fins d=1mm: Nickel plated copper 1.0 mm instead of 0.5 mm. The Max. Power Dissipation will be increased by ~80 %. For air and liquid cooling (e.g. Galden® or oil).

CF-X2

Non-Isolated Cooling Fins enlarged by x2: Fin area enlarged by factor 2. Not relevant in connection with liquid cooling.

CF-X3

Non-Isolated Cooling Fins enlarged by x3: Fin area enlarged by factor 3. Not relevant in connection with liquid cooling and forced air convection.

CF-CS

Non-Isolated Cooling Fins with customized shape: Individual shape to meet specific OEM requirements. (2)

CF-LC

Non-isolated Cooling Fins optimized for liquid cooling: Double fins, nickel plated copper, 0.5 mm thickness, height 20 mm.

CF-DR

Cooling Fin for Driver: Small extra cooling fin for the control electronics. On ground potential. Can be necessary in combination with HFS. (2)

GCF

Grounded Cooling Flange: Nickel-plated copper flange for High Power applications. Max. isolation voltage 40kV. Increased coupling capacitance C_C. In combination with option SPT-C only.

GCF-X2

Grounded Cooling Flange, Max. Continuous Power Dissipation increased by x2:  Thermal resistance “Switch to Flange” reduced for twice the power capability. (2)

GCF-W

Water Cooler for Grounded Cooling Flange:  Flat water cooling plate attached to the grounded cooling flange GCF. With water inlet and outlet.

DLC

Direct Liquid Cooling:  Internal liquid channel in direct contact with the power semiconductors. Very compact cooling solution for medium power. Galden® and non-conductive liquids only. (2)
