The Transformer Upgrade is used to upgrade a machine to the next highest tier of input power. Upon placement in an upgrade slot on any Industrial Craft machine, it will increase that machine's input tolerance up to the next tier.
Be sure you apply the Transformer Upgrade(s) to your machines before connecting a higher tier power input to them. Connecting the power before you apply the upgrade will result in the machine's explosion.
Also mind in SMP players can fiddle with machine upgrades despite zone protection. The result is a cascade of exploding machines.
One upgrade enables a tier 1 LV (32 EU/t) machine to accept a maximum current of 128 EU/t (MV). Two upgrades will allow the same machine to accept a maximum current of HV (512 EU/t). Finally, three upgrades will allow a simple Macerator to accept Extreme Voltage current, a whopping 2048 EU/t. Putting in a fourth upgrade will not allow a machine to accept higher than EV, such as from a Nuclear Reactor. It will blow up regardless of the upgrades, making four upgrades in one machine completely useless.
Machines which support usage of the Transformer Upgrade include:
|Electric Furnace||Note the Induction Furnace does not support upgrades|
