Voltan ini terlalu rendah.

• voltan = voltage
• ini = this
• terlalu = too / excessively
• rendah = low

So the structure is basically this voltage too low, which in natural English becomes This voltage is too low.

In Malay, demonstratives like ini (this) and itu (that) usually come after the noun.

• voltan ini = this voltage
• voltan itu = that voltage

This is a very common pattern in Malay:

• buku ini = this book
• rumah itu = that house

So voltan ini is the normal word order.

Malay often leaves out the verb to be in simple sentences like this.

So:

• Voltan ini terlalu rendah literally looks like:
• This voltage too low

But it naturally means:

• This voltage is too low

This is normal Malay grammar. You do not need a separate word for is here.

Terlalu means too in the sense of more than is acceptable, more than desired, or excessively.

So:

• terlalu rendah = too low

This suggests there is a problem. It is not just describing the voltage as low; it says the voltage is lower than it should be.

This is an important difference:

• terlalu rendah = too low
  → implies a problem or something undesirable

• sangat rendah = very low
  → just describes the degree; it does not automatically mean it is a problem

So if you want to say the voltage is lower than acceptable, terlalu is the right word.

No. Malay adjectives do not change for gender, number, or case.

So rendah stays rendah no matter what noun it describes or follows.

Examples:

• voltan rendah = low voltage
• harga rendah = low price
• dinding rendah = low wall

There is no adjective agreement like in many European languages.

No, that would sound wrong.

In Malay, degree words like terlalu normally come before the adjective:

• terlalu rendah = too low
• terlalu tinggi = too high
• terlalu mahal = too expensive

So Voltan ini terlalu rendah is the correct order.

Normally, no. The most natural standard structure is:

• voltan ini = this voltage

Putting ini before the noun is not the normal pattern for ordinary sentences like this. A learner should strongly prefer:

• Voltan ini terlalu rendah

Just change ini to itu:

• Voltan itu terlalu rendah = That voltage is too low

So the contrast is:

• ini = this
• itu = that

For adjectives like rendah, Malay normally uses tidak, not bukan.

Examples:

• Voltan ini tidak rendah = This voltage is not low
• Voltan ini tidak terlalu rendah = This voltage is not too low

A useful rule of thumb:

• tidak is used with adjectives and verbs
• bukan is usually used with nouns

Voltan is a standard Malay technical term. It is the normal word used for voltage in formal Malay.

Like many scientific and technical words in Malay, it comes from international scientific vocabulary, but it is still a proper Malay term.

So in technical or educational contexts, voltan is completely normal.

A simple learner-friendly guide would be:

• voltan → VOHL-tan
• ini → ee-nee
• terlalu → ter-la-LU
• rendah → ren-DAH

A few notes:

• r in Malay is usually trilled or tapped more than in most English accents.
• h in rendah is pronounced lightly.
• Malay pronunciation is generally quite regular compared with English.

No. Malay does not use articles in the same way English does.

So voltan can mean voltage, the voltage, or a voltage, depending on context. In this sentence, ini already makes it specific:

• voltan ini = this voltage

That is why no extra word for the is needed.
