Isolated Variable AC Power Supply The XP-810 is an isolated-variable AC power supply. The voltage output is 0 - 140VAC at 3 amps continuous or up to 4 amps intermittently. The unit has a built-in isolation transformer for safe servicing of “hot chassis sets”. The unit features a four inch meter to monitor voltage and current. The Model XP-810 also has a triac circuit to vary the voltage to a soldering iron, keeping it at any desired temperature. The XP810 is an isolated-variable AC power supply ideal for troubleshooting equipment at normal, low and high line voltages. It also features a built-in soldering iron temperature control and power line leakage tester. Features: • Variable Isolated Output (0 - 140VAC) • Power Line Leakage Test • Circuit Breaker • Overload Protection • Built-in Soldering Iron Temperature Control • 2 Meter Range of 2A and 4A for Accurate Readings • Built-in 4” Meter
