Range B Service and Utilization Voltage Range B includes voltages above and below Range A limits that necessarily result from practical design and operating conditions on supply or user systems, or both. Although such conditions are a part of practical operations, they shall be limited in extent, frequency, and duration.
Table 3 - AC three-phase systems having a nominal voltage above 1 kV and not exceeding 35 kV and related equipment The recommended voltages in the Philippine Electrical Code were based on North American standards although some projects in the Philippines use IEC standard voltages.
For low-voltage installations, this voltage drop is limited to 4%, therefore, the utilization voltage range is +10%, -14% (Note 1). This utilization range should be taken into account by Product Committees. Note 1 At the end of the transition period, the reduction of this range will be considered.
The DSL power system may supply both higher voltage analog line drivers and amplifiers (typ. +/-12V) and several low voltage supplies required by the digital ASIC (+5V, +3.3V, +1.8V, +1.5V).
