TYPE DESIGNATION (HOW TO ORDER)

SVC 471 D-14A FF 7

SVC

SVC series Varistors are gapless ceramic surge absorbers of a new type made of metal oxide which is designed to protect

various kinds of electronic devices and semiconducting elements from surges.

󳢯INTRODUCTION

1. High discharge current capability up to 4000 Amps.

2. Excellent clamping characteristics.

3. Fast response time under 50 nanesesconds.

4. Improve product safety

5. UL, CSA, VDE recognized

Notes :

①The waveform of the maximum DC applied voltage is flat. When a ripple

voltage as from a rectifier source is supplied make sure that the peak

voltage is kept under th Vdcm

An AC applied voltage(50/60Hz) form a since waveshape.

When the distortion in the waveform is extensive make sure that the

peak voltage is less than

2

times the Vacm.

②Energy : Wtm

Transient energy ratings are given in the Wtm column of the

specifications in Joules (watt-second).

The rating is the maximum allowable energy for a single impulse of 2ms

square-waveform current with continuous voltage applied. Energy

ratings are based on a shift of Vnom of less than ±10% of initial value.

③Transient peak current (ltm)

The peak current rating. ltm. of varistor is based on an 8/20㎲ test

impulse waveshape.

√

This peak current is the maximum peak current in which the nominal

varistor voltage shift does not exceed ±10% when the test impulse is

applied twice at 5 mimutes intervals.

④Nominal varistor voltage : Vnom

Indicates the varistor terminal voltage measured with a 1mA DC applied.

-0.1mA DC in the case of the 0.5A and 05B series.

⑤Maximum clamping voltage : Vc

Indicates the peak teminal voltage measured with an 8/20㎲ impulse

current applied.

󳢯Operating ambient temperature : -40℃ to +80℃

Varistor voltage selection table (ZL)

Notes :

①The power supply voltage must not exceed the maximum

allowable circuit voltage.

②Since independent wiring loads and capacitive loads cause the

voltage build-up at the time of opening or closing the load, use SVC

having a varistor voltage as high as possible.(󳢮mark)

③The bold faced portions of the type letters vary.

Notes :

The varistor SVC has a capacitance value. Take not of this when

applying them to high-frequency signal circuits.

Protection of relay

(Contact coil)

Protection of

semiconductors

Notes :

①When subjected to megger testing (500V DC), the insulation

resistance value can decrease due to the leakage current of the

SVC, To avoid this remove the varistor or use󳢮marked SVC.

②When subjected to dielectric strength test(1000V AC). remove the

SVC or use󳢮󳢮 marked SVC.

Select varistors taking a note of operating conditions peculiar to the

equipment. Notes :

①The power supply voltage must not exceed the maximum

allowable circuit voltage of the SVC

②Pay due attention to the surge energy generated by the load.

③Select SVC referring to the pulse lifetime rating.

④To further reduce the tendency of sparking across the contacts

connect a capacitor parallel with the SVC. This will also protect the

equipment from electromagnetic wave jamming.

1. Overcurrent protection

When surges exceed the rating for the SVC, short-circuits or

damages can be expected. Take following precautions.

2.Installation

① When operated at location near heating element or exp-

osed to direct sun light, confirm that the the ambient

temparature range.

② When operated in dusty or dirty locations, or exposed to

corrosive atomospheres, or where metallic powders or salt

can be expected, be sure to mount within a protective enclo-

sure.

3. Molding

5. Electrical Characteristics

4.Current, power and energy rating vs, temperature

When shielding the SVC in a resin molding, take a note of the

materials used and temperature, since they influence the

reliability. For further information please contact SAMWHA

Operating ambient temperature -40℃ to + 85℃

Storage temperature -40℃ to + 125℃

Voltage temperature coefficient -0.05%℃

Insulation resistance(at500V) Over 1000MΩ

① Connect the SVC at a position nearer to the equipment

than the overcurrent protection device “Ⅰ”(fuse, MCCB) as is

shown in the diagram.

When the SVC is shorted, the overcurrent protection device

“Ⅰ”operates (trips or blow off the fuse).

② If the overcurrent protection device “Ⅰ”can not be in-

stalled in “Ⅰ”position, connect a fuse at “Ⅱ”position. Select

fuse rated current for the SVC referring to the following table.

③ When “Z2”SVC is connected between the equipment and

ground install an ELCB (Earth Leakage Circuit Breaker). If

not possible, connect a fuse or thermal fuse at “Ⅲ”position.

Varistor Terminology

󳢯Varistor Voltage : Vnom

Varistor peak terminal voltage

measured with a specified current

applied

The DC current applied is 1mA

normally.

󳢯Clamping voltage : Vc

Maximum terminal voltage (peak

voltage across the varistor)

measured with an applied 8/20㎲

impulse of a given peak current.

󳢯Capacitance

Typical values measured at a test

frequency of 1kHz

󳢯Rated peak transient current

: itm

Maximum peak current through the

varistor with line voltage applied.

The maximum peak current with in

the varistor voltage change ratio of

±10% with the standard 8/20㎲

impulse current applied two times

at 5 minute interval.

󳢯Rated transient energy : Wtm

Maximum allowable energy for a

single impulse of 2ms square-wave

current waveform with rated contin-

uous voltage applied. Maximum

energy rating base on a shift of

Vnom of less than ±10% of initial

value.

󳢯Pulse lifetime rating

This is expressed as the maximum

allowable number of impulse curr-

ents applied.

8/20㎲ impulse current (or 2ms sq-

uare wave) is applied at prescribed

interval.

This curve also provides for

derating current as required with

repetitive pulsing.

󳢯Tset current waveform

Characteristics tests for Varistors

are carried out by using 8/20㎲ test

impulses Data such as the

maximum clamping voltage(Vc)and

the transient peak current(ltm) are

obtained by using this impulse

current.

However, for the Vc characteristics

of the Axial package type a 10mA

DC squarewave current is used to

cary out the test.

󳢯Rated RMS Voltage : Vacm

Maximum continuous sinusoidal

RMS voltage at 50/60Hz which

may be applied.

󳢯Rated DC Voltage : Vdcm

Maximum continuous DC voltage

which may be applied.

󳢯Rated average power dissipation

: Ptam

Maximum average power that can

be applied within the specified

ambient temperature.
